Software and Hardware Release Notes

Various changes have been made to the HyperWorks 10.0 software packaging including the HyperWorks products, hardware support, installation, invoking, and online help. Beginning in HyperWorks 9.0, all applications were switched from HyperWorks Units to a new licensing system called GridWorks Units (GWU). GridWorks Units work much like HyperWorks Units with one main difference: one HyperWorks Unit is equivalent to 100 GridWorks Units. This change allows for the pricing of less expensive Altair products within the same unit-based licensing system. The detailed changes made to the Altair licensing system are documented in the Altair Licensing Release Notes.

Software Additions and Changes

ScriptView Altair ScriptView is an Integrated Development Environment (IDE) for producing and executing custom scripts.

It takes 600 GridWorks units to load ScriptView.

HyperMath Altair HyperMath is a scripting language coupled with a set of libraries designed for numerical coding.

It takes 600 GridWorks units to load HyperMath.

HyperStudy/HyperStudyDSS HyperStudy and HyperStudyDSS have been consolidated into one application, HyperStudy.

Utility/Tools The Tcl/Tk version has been upgraded to Tcl/Tk 8.4.16 for Windows.

Support for IBM AIX 5.3 has been dropped for HyperWorks GUI applications.

Enhancements

Installation and launch On UNIX and Linux operating systems, HyperXtrude is installed with the HyperWorks solver package.

The HyperWorks solver package is no longer an add-on package. It can be installed as a standalone software.

The server/client installation on Windows has been improved.

The uname -m command, a more universal standard of Linux, can now be used for checking Linux machine types.

Updates to Mainwin 5.2 provide support for the latest Linux platforms: RHEL 5.2 and SLED 10 SP1.

HyperWorks help A print button is now available on each help page that allows you to print topics.

The navigation path of the current help topic is now displayed above the topic title.

The latest HyperWorks help content is posted on the HyperWorks web site (www.altairhyperworks.com) under the Support page.

The help content for HyperWorks Solver and CAD Interfaces has been moved into the HyperMesh, HyperView, and HyperGraph help systems.

As with the products, HyperStudy and HyperStudyDSS help has been consolidated into one help system (HyperStudy).

Resolved Issues

Installation and launch The HyperWorks installation issue related to not finding the gtar within our installer when the UNIX system fails to have gtar present has been resolved.

HyperView can now be launched when the ABAQUS ODB API is not installed.

HyperWorks can now be installed on a machine containing a large amount of disc space.



hw_sysinfo no longer fails to provide a report. The requirement of setting the variables for the

online help browser in order to run the OptiStruct job without warning messages has been eliminated.

The HyperWorks client installation on Windows no longer requires write access to the NETSETUP folder on the server machine where the HyperWorks server installation resides.

HyperView and HyperGraph no longer conflict and fail to invoke on a Linux machine where the WINE API is installed and exists in the PATH variable.

The command line error message (unknown test operator) when invoking HyperWorks on HPUX 11.1 has been corrected.

Known Limitations

Installation and launch Installing and launching HyperWorks 32 bit GUI applications on a 64 bit Linux platform is not recommended.

HyperView Player is not available with Windows based software server installations.

Help browsers On UNIX machines, the help does not work on old versions of browsers.

On Internet Explorer, links to open the PDF files may not work. As workarounds, you can save the file to a local directory or save the file path as a Favorite.

Utilities In Windows based software server installations, HW_Inventory can be run from software server clients, but not from the server.

Some files listed in the HW_Inventory results file do not show version tags.



Altair Licensing Release Notes

Beginning in HyperWorks 9.0, all applications moved from HyperWorks Units to a new licensing system called GridWorks Units (GWU). GridWorks Units work much like HyperWorks Units with one main difference: one HyperWorks Unit is equivalent to 100 GridWorks Units. The GridWorks licensing system was designed to enable HyperWorks Partner Products (selected third party products) to be licensed via GridWorks Units. As part of the license agreement that enables partner software to be used, product usage data must be sent to Altair. The Altair GridWorks License package is separate from the HyperWorks application package and contains both the FLEXnet license manager and usage report tools.

Altair Licensing

New Features

GridWorks licensing The Altair licensing system now uses GridWorks Units (GWU). The following changes apply: A new feature, GridWorks, has been added for

license units. 100 GridWorks units is equivalent to one

HyperWorks unit. A new set of global license features has been

added: GlobalGridWorksAM, GlobalGridWorksEU, and GlobalGridWorksAP.

HyperWorks 9.0 (and later) applications will recognize GridWorks Units only.

License usage tracking The licensing usage monitor and report tools (UMT and URT) are included in the 9.0 and above License Manager package. UMT and URT record the usage of each feature and send a report back to Altair on a monthly basis. The usage log files that are generated are in plain text.

Partner software Licensing features for HyperWorks Partner Software are implemented in the Altair licensing system. This allows partner software to use an Altair GridWorks license and check out GridWorks units.

License files The tracking features listed in the license file are now required to launch a HyperWorks application. Without the tracking feature, the associated HyperWorks application will not invoke. Also note that the number of units of each tracking feature will be 2147483647, by default. This is for the UMT/URT and proper tracking.



License Manager License Manager is based on FLEXnet Publisher V10.8.0.

License Manager has its own package and is not bundled with the HyperWorks application packages.

License Manager supports the platforms supported by all Altair products, including HyperWorks.

Resolved Issues

License Manager/UMT/URT The issue related to Automatic Heartbeat has been corrected.

Reliability has increased in several areas for UMT and URT.

UMT and URT are more robust with multiple UUID strings in license files.

The URT transfer issue on platforms with older JDKs has been resolved.

The UMT polling interval on Windows now works properly; Correct values are now calculated for usage.

Licensing System - Installation, Hardware, and Invoking

Removed Features

Operating systems Windows 2000, HP ITANIUM HPUX11-23, IBM AIX 5.1, SGI IRIX, and Linux RedHat EL3.0 are no longer supported by the HyperWorks GUI applications.

Enhancements

UMT and URT Several UMT/URT reliability issues have been fixed. UMT now properly handles multiple UUID in a single

license file.

Added manual URT option: When invoked with urt.bat m, the prepared usage files are placed into the directory specified in the ALUS.CONF file.

Installation and launch An upgrade option has been added to the License Manager installation to keep older configurations and



allow the installation of new software.

Known Limitations

License Manager FLEXnet 10.8 does not support the Vista32 or 64 bit platform. To make it work, replace the lmutil, lmgrd and lmtools executables from FLEXNet 11.4.

Vendor daemon The License Manager vendor daemon (altair_lm) may fail to start on Solaris and HPUX machines, due to insufficient file descriptors. Increasing the hard limit and soft limit of the maximum number of file descriptors available for the license manager (lmgrd) process to 1024 helps resolve this issue.

Multiple license pools There is a limitation on HyperWorks leveling when working with multiple license pools. This limitation occurs due to the following FLEXlm characteristics:

Each license pool functions independently of other license pools and cannot communicate with any other license pool.

The application tries all license servers in the order in which they are listed in the ALTAIR_LM_LICENSE_FILE or LM_LICENSE_FILE environment variables. The first available license server that can grant licenses is used for checkout.

A license pool is a collection of licenses that could consist of a single license server or a cluster of redundant servers. Within a single license pool, you can launch multiple HyperWorks applications on the same host and with the same display with the number of licenses consumed being equal to the number required by the application with the highest draw of licenses. If launching new HyperWorks applications by the same UHD causes licenses to be drawn from a license pool other than the one previously checked out (perhaps because the first license pool has run out of licenses), additional HyperWorks units are checked out from the second license pool, thus stacking the licenses.

For a tri-server redundancy licensing setting, it is recommended that all three servers are physically located close to each other, and on the same subnet. Placing three servers in different geographical locations is not recommended by FLEXNet.



When working with three server license pool configurations, licenses can be leveled on UNIX (in most cases) by setting the HW_POOL_SECURITY environment variable to 1.

lmborrow option The lmborrow option used to borrow mobile licenses only works for products that do not stack licenses.

A borrowed license listed in LMTOOLS is not automatically updated when the license expires.

LMTools On Windows, the GUI for lmtools ignores the following environment variables when launching lmgrd:

ALTAIR_NOLOG ALTAIR_LOGFILE ALTAIR_LOG_INTERVAL

As a workaround, start lmgrd from the command line.

CATIA ttflicense file If you require any of the CATIA V4/V5 readers, you will need to have the ttfLicenseFile.txt installed. The current license can be obtained from the Hyperworks support site.

The ttfLicenseFile.txt file MUST reside in the current working directory from where lmgrd is launched. Note that this is different than being in the same directory, although by default all of the Altair supplied startup scripts set their current working directory to where the license file is before starting lmgrd. Assuming lmgrd, the main license file and the ttfLicense are in the same directory, simply cd to that directory before starting lmgrd. On windows, set the services startup directory to that location.

HyperWorks Application Licensing

New Applications

HyperMath This new application uses 600 GridWorks units.

ScriptView This new application uses 600 GridWorks units.



Enhancements

OptiStruct - Parallel solution (SPMD)

The GWU required to run OptiStruct parallel solution is based on the number of cores used:

1-4 cores 5-8 cores 9-16 cores 17 and higher

5000 GWU 7500 GWU 10000 GWU 15000 GWU

RADIOSS Block format - SPH and ALE analyses

The analysis now uses 2500 GWU instead of 3800 GWU. The tracking feature has been changed from RadiossB to RadiossA.

Resolved Issues

Licensing The robustness of how HyperWorks Solvers (OptiStruct, RADIOSS, and MotionSolve) level and stack GridWorks units under the same UHD (User, Host, and Display) has been improved.

An error no longer occurs when HyperStudy levels and stacks while launching multiple applications.

An error no longer occurs when HyperCrash levels and stacks while launching multiple applications.

To run RADIOSS parallel solution (SPMD, Single Process Multiple Data) on 33-64 cores requires 7500 GridWorks units. To run the job on 65-128 cores requires 10000 GridWorks units.



HyperMesh 10.0 Release Notes

Altair HyperMesh is a high-performance finite element pre-processor that provides a highly interactive and visual environment to analyze product design performance. With the broadest set of direct interfaces to commercial CAD and CAE systems, HyperMesh provides a proven, consistent analysis platform for the entire enterprise. Focusing on engineering productivity, HyperMesh is the user-preferred environment for all CAE modeling tasks ranging from geometry clean-up to high-quality automeshing and analysis set-up.

Altair HyperMesh 10.0 offers many new features that will further improve and automate your CAE processes, including the new optimization browser view, significant updates to meshing (SPH, Shell and Solid), and the new 1D element visualization. See 10.0 API Programmer's Guide for a list of updates to the API commands.

Browsers

New Features

New and improved Model Browser

In the Model Browser, the interactive entity control capability between the browser list and the graphics area now supports all HyperMesh entities. The Selector, Show/Hide, and Isolate browser action modes now work for all entities that have display control. Finding entities and their related properties via graphic selection is very quick and efficient allowing for further editing and querying control of entities.

New optimization browser view The introduction of the optimization model browser view allows you to setup multiple optimization problem definitions within a single HyperMesh session. Easy to use drag-and-drop functionality allows for very quick optimization problem setup by moving the optimization definitions from the optimization repository to the optimization problem definition. Multiple optimization setups can be saved to the .hm file; in addition, there is also export control so that only a single optimization problem can be exported at any one time. See Model Browser for a complete explanation of the Model Browser.



CAD Translators

New Features

Support for UG NX6 Support has been added for UG NX6 on Win32/Win64. NX and NX2 readers have been removed.

Naming control option when importing Catia files

The option, @SplitComponentsByChild, has been added in the CATIA reader to replicate the part/child naming structure and organization of the CATIA model using HyperMesh assemblies/components. Individual entities are organized into the relevant components, with the components being organized into relevant assemblies.

New API commands to calculate the physical properties of solid geometry

New API commands have been added to calculate the physical properties of solid geometry (volume, center of gravity, moments of inertia, mass). For all CAD readers, the @LoadMassAttributes option will no longer create metadata for the following values:

.ALTAIR.HW..CG

.ALTAIR.HW..INTERTIA_PRODUCTS

.ALTAIR.HW..MOMENTS_OF_INERTIA

.ALTAIR.HW..MASS

.ALTAIR.HW..VOLUME

As an addition, the CATIA, Parasolid, Pro/E, and UG readers will create metadata for the density if it is available in the CAD model in the format .ALTAIR.HW..DENSITY.

New option to read tags as metadata

The option, @TagsAsMetadata, has been added to the CATIA, IGES, Pro/E, UG, and VDAFS readers for importing tags (names) as metadata attached to the relevant entities.

Enhancements

Improved solid geometry import performance

The performance of solid geometry import for the CAD readers that import solid entities has been improved.



Connectors

New Features

New and updated Connector Realizations

RADIOSS (Block) bolt (general) hinge bolt (spider) bolt (cylinder rigid) bolt (cylinder spring) adhesive spring

RADIOSS (Bulk Data) and OptiStruct sealing bush rbe3 (load transfer) adhesive hexa (adhesive)

Abaqus acm (detached-(T1+T2)/2 acm (shell gap) adhesive bolt (b31) hinge (b31) rbe3 (load transfer)

LS-DYNA spot - mat196 hexa (adhesive - shell gap)

Nastran sealing bush rbe3 (load transfer) adhesive hexa (adhesive)



Adhesive support to connector property scripts

Adhesive support to connector property scripts has been added for: prop_abaqus_acm.tcl prop_nastran_acm.tcl (called prop_acm.tcl in

HyperMesh 9.0) prop_type2.tcl

Solid bolt hole support Bolt connectors can now realize to solid elements and will attach every node within the solid hole. This is the default behavior.

If you would like to revert to the old behavior (just tying to the top and bottom rings) you can edit the hm.cfg file by adding the line *ce_fe_solid_bolt_setup(0).

Seam adhesives A new capability for creating adhesive realization using seam connector (building continuous hexa using lines as input) has been implemented. The adhesive parameters such as the width, thickness, and number of strips along the width and thickness can all be defined during realization. This is more flexible than the area connector feature.

Seam adhesives are supported from the panel and can also be read in from a connector MCF.

Assemblies as links In addition to components, elements, nodes, and tags, assemblies are now supported as link entities for connector realizations

Enhancements

Easier loading of property script for custom weld types

A search for the property script now occurs in the directory from which the feconfig.cfg file is first loaded.

Realization performance The RADIOSS type2 realization performance has been improved.

Improved DOF support DOF is supported for more 1D element types including weld, rigid, spring, and bars.



Geometry

New Features

Midsurfacing R/T parameter Midsurfacing R/T parameter is a new feature to control midsurface extraction for T- and X-connections. This provides better control of midsurface extraction for these types of connections.

New panels and functionality lines > offset subpanel This new line offset functionality is combined with the old midline subpanel. This functionality allows lines to be offset along their direction of curvature either continuously or variably. Options also exist to specify the start point of the line and the type of line to create when the direction of curvature changes within the line.

surfaces > fillets subpanel This creates constant width fillets across shared surface edges. Controls allow the original geometry to be trimmed, deleted and stitched, or simply for the new fillet surfaces to be created without modifying the original input surfaces.

solids > drag along line sub-panel Solids can now be created by dragging one or more input surfaces along a line. Advanced options include the ability to move the location of the drag line, drag along the line +/- direction, control the way in which the surface is dragged (frame mode), and specify the solid splitting and organization based on the input surfaces. (drag along normal and drag along vector are also separated out as sub-panels.)

Meshing

Solid Meshing

TetraMesh Process Manager Template

Tetramesh Process Manager Template is a new process based tool to enable users to tetramesh models in a reduced timeframe. Significant time reductions can be achieved when using the tool to tetmesh CAD data. A typical example is a powertrain application, however the tool is designed to be a generic aid for tetmeshing. The main bulk of tetmesh model build time is usually spent in cleaning and



organizing geometry. Within the tool, there are specific steps to help guide you through various operations such as organizing surfaces around holes, and fillet recognition and handling. These features can be treated separately from the rest of the model, for example you can have a very specific mesh criteria whereas the rest of the model can have a more relaxed mesh criteria where the feature capture is less critical.

Interactive solid map meshing Improvements to the solid map functionality include a new capability that exposes full interactive mesh editing control of the solid before solid map mesh generation. After solid selection, the solid map panel takes you into the interactive mode where you can control the mesh density, element type, and mesh method before creating the solid mesh.

Sliver tetra element fix Fix Sliver Tetra Elements is a new tool that fixes all sliver and wedge elements based on a pre-defined 3D mesh criteria. There are numerous options that allow the boundary nodes and internal nodes to move, as well as options that allow complete control over whether you wish to fix either sliver or wedge, or both types of elements. The functionality is located in the Geom/Mesh utility menu.

Enhancements

Updates to Fix 2nd Order MidNodes utility

Fix 2nd Order Midnodes utility has been updated with options to allow movement of the internal middle nodes and an option to move boundary nodes along geometry first or move off geometry, if required.

Surface Meshing

New Features

Mesh flow functionality New mesh flow functionality has been introduced in the automesh panel. The flow:align option produces a more orthogonal quad dominated mesh. The flow:size option in conjunction with the align option enforces the global mesh element size with minimal min/max element size variation. Both options improve the flow of the mesh and also improve QI element quality.



Automesh using free lines Automesh using free lines is a new feature where instead of using the feature edge or automatic feature edge detection, you can use the lines option. When remeshing, you can define a line that may or may not be on the plane of the elements, and upon remeshing, the mesh ensures that there is node seeding along the chosen free line.

Shrink wrap meshing Shrink wrap meshing now includes an option to enable solid mesh generation. The new generate solid mesh option is available for both the Loose and Tight shrink wrap algorithms the output is an all hexa mesh model. There is an additional parameter called minimum jacobian; this option essentially controls the proximity of the solid mesh to the original features while ensuring the solid mesh meets the pre-defined element quality. The tight algorithm has been improved to capture more features without the need to manually define features. The performance for ShrinkWrap has also improved.

SPH meshing SPH meshing (for RADIOSS Block, LS-DYNA, and PAM-CRASH) is a new functionality used to generate Smooth Particle Hydrodynamics (SPH), Finite Point Method (FPM) elements. SPH/FPM elements are used for analyzing bodies that do not have high cohesive forces among themselves and undergo large deformation, such as liquids and gases. The SPH/FPM elements are given a pre-defined density or total mass. There are additional features that allow a partial fill of the selected volume along with direction control for the partial fill. The functionality is accessible via the 1D > sph panel in the RADIOSS (Block), Ls-dyna, or Pamcrash user profiles.

OSSmooth multi-layer auto-bead generation

OSSmooth has been updated to support two-layer auto-bead generation. The benefits of the two-layer auto-bead functionality include significant improvements to the interpolation of the topographical results. As a result of the updates to the isosurface generation, OSSmooth performance has improved. Remeshing is now available for both auto-bead and isosurface parameters. The parameters in the .oss file format have also been reorganized; the ability to turn on/off auto-bead and isosurface parameters separately is now available.



Enhancements

Improvements to Add Washer, Trim Hole, Fill Hole, and Bead utilities

Add Washer, Trim Hole, Fill Hole, and Bead utilities have been updated and are now included in core HyperMesh functionality. As a result, the robustness, performance, and quality of meshed output has significantly improved when comparing the same feature in previous releases of HyperMesh.

CFD Meshing

New Features

CFD meshing updates The robustness of the algorithm has been improved; more use cases are now supported. Within the latest version there are also updates to the surface projection and tolerance algorithms.

The boundary layer thickness of the resulting mesh is closer to the user-defined target than in previous releases. In general, the boundary layer thickness variation on uniformly curved regions should be within 10%.

Unoffsetable nodes for regular tetra meshing with quad transitions can be handled.

Batch Meshing

New Features

Mesh flow functionality New mesh flow functionality has been added to the batchmesher, the flow:align and flow:size functionality is accessed via the Criteria and Parameters File Editor > Parameters tab.

Improved feature capture - preserve rounded bead midline

The Preserve rounded bead midline option has been added, which forces nodes to be placed along the midline of a rounded bead the functionality is accessed via the Criteria and Parameters File Editor > Parameters tab.



Penetration Check

Enhancements

Performance improvements Multithreading for penetration and intersection check has been added. For multi-core machines, the performance gains are considerable now that the penetration check utilizes all available CPUs. The performance improvements vary per model and machine specification; typically, you could expect a performance improvement between 40% - 70%.

Miscellaneous

New Features

1D element visualization A new 3D graphical representation has been introduced for all displayed 1D elements. The primary purpose of this functionality is to allow you to visually verify that model data is correctly entered instead of having to review the text details of the element and property card images to do the same. 1D elements properly visualize beam section geometry, orientation, and offset, at both ends A and B. Only constant beam section and thickness elements are considered. Graphics selection, pre-highlighting, and highlighting for the 3D graphical representations behave as their 1D counterpart representations.

New visualization GUI The old style visualization pop-up has been replaced with a new visualization GUI for controlling visualization options for connectors, constraints, loads, morphing, topology, systems, and vectors.

Enhancements

Graphics updates New graphics representation for mass/0D elements. The mass/0D elements are now represented by a very small sphere; the mass/0D element display is treated the same as all other element or component display.

API updates Numerous API requests and enhancements have been included; review 10.0 API Programmer's Guide for further details.



Morphing

New Features

Kriging based morphing Fast and smooth multi-directional morphing without solving for local influences (see morph options > set domain solvers) is included.

A mesh can now be smoothly interpolated to approximately fit through a given set of nodes or analytic surfaces described by algebraic equations (see map to geom > map a mesh to fit an interpolate surface).

Equation based mapping and morph constraints

Mapping and constraining domains, nodes, and morph volume edges to analytic surfaces described by algebraic equations can now be performed (see map to geom and morph constraints panels).

FEA based morphing Direct access to the linear and non-linear finite element analysis solver RADIOSS allows you to replicate the behavior of physical material while morphing (see morph options > set domain solvers).

Morphing quality check The element quality index can now be plotted using colors and legends.

Enhancements

Morph panel Handles may be scaled with respect to a node or with respect to the centroid of selected handles.

Handles on morph volumes may be moved along, and extended beyond morph volume edges.

Handles may be projected to a line, plane, surface, or mesh.

While interactively morphing on a plane, the plane can be inferred using the selected handles.

Morph volumes Morph volumes can be created by dragging along a line, vector, or about an axis. You may also drag existing morph volumes or use elements as a base.

Morph volumes can be created using symmetry.



You can now map morph volume edge to line, surface, mesh, and equation (map to geom).

A mid-side handle can be added to an edge by clicking on a particular position on the edge as well as deletion of mid-side handles.

Handle locations can be interactively manipulated along the morph volume edges (morph panel).

Tangency can be applied among multiple morph volumes rather than edge-by-edge.

Morph volumes can be equivalenced with a specified tolerance.

Split location can be specified using a node on the model mesh.

Connector support You can now turn off and on morphing of connectors outside domains.

Connectors can be morphed by type, for example, bolts and welds as clusters where as, seams as stretchable.

Connectors can be rotated while morphing via spin, tilt, and full rotation.

An option for mesh stretching around 1D domains and connectors solved as clusters has been added.

Map to geometry You can interpolate surface function for mapping a mesh to, or creating a mesh through, a surface interpolated from nodes or lines.

Support for mesh under surface difference in order to morph from surface-to-mesh, mesh-to-surface, and mesh-to-mesh has been added.

Blending through the mesh option has been added for section mapping, line difference, surface difference, and normal offset.

Several new line projection options for map-to-sections and line difference have been added.

The robustness of section mapping has been improved.

Morph constraints The vector/plane normal can be plotted during morph constraint review.

Cluster constraints can be rotated via spin, tilt, and full.

Generic shape for model type constraints such as length, volume, angle, and radius can be



automatically generated. Options have been added for extended edges and

depenetration for on elements type constraint.

Shape panel You can now convert shapes to enforced displacements and vice-versa.

The ability to apply translate, position, and reflect shapes to selected nodes has been added.

There is now a separate sub-panel for animate shapes.

Graphical user interface Picking of morphing entities in hidden line graphics has been greatly improved.

Morph constraints and morph volumes are now available from the renumber panel.

RADIOSS 10.0 Release Notes

RADIOSS is a state-of-the-art finite element solver uniting implicit and explicit integration schemes for the solution of a wide variety of engineering problems, from linear statics and linear dynamics to complex nonlinear transient dynamics and mechanical systems. This robust, multidisciplinary solver enables designers to maximize performance related to durability, NVH, crash, safety, manufacturability, and fluid-structure interaction, in order to bring innovative products to market faster. RADIOSS 10.0 again brings much advancement over previous versions, with emphasis in the areas of performance, frequency response analysis, acoustic response analysis, fatigue analysis, and contact modeling.

General

Resolved Issues

License stacking The licensing mechanism on Windows and Linux operating systems no longer stacks licenses when they should be leveled.

RADIOSS Bulk Data Format

New Features

Parallel solution (SPMD) on Linux

A parallel solution has been implemented on Linux platforms for linear static, linear buckling, and direct frequency response subcases.

Models containing only these subcase types may be solved in parallel across multiple nodes. If other subcase types are present in the model, all subcases will be solved in series on one node.

The parallelization technique is Single Program Multiple Data (SPMD), and uses the message passing interface, HP-MPI.

Sensitivities related to these subcase types are also solved in parallel.

Iterative solver (PCG) An iterative Preconditioned Conjugate Gradient (PCG) method is now available for the solution of linear static problems.

This solver may be selected at the subcase level using the SOLVTYP selector.



This iterative solver may provide significant performance gains over the traditional direct solver for large solid models.

Fluid super-elements Component Mode Synthesis (CMS) may now be used to generate external superelements (DMIG) for combined fluid-structure models.

Free convection The linear steady-state heat-transfer solution is enhanced with a free convection boundary condition.

The boundary condition (CONV) may be defined on thermal surface elements (CHBDYE) allowing thermal communication between a structure and the ambient environment.

Internal heat generation The linear steady-state heat-transfer solution has been enhanced to consider internal heat generation.

A volumetric rate of heat generation (QVOL) may be defined for a list of heat conduction elements.

Strain-life fatigue analysis A strain-life solution has been implemented for fatigue analysis.

The implementation uses the Neuber correction together with a cyclic stress-strain curve and a hysteresis loop equation to get stress/strain under cyclic loading. An equivalent strain approach is applied to query life from strain-life curve.

Contact interface definition A new contact interface definition (CONTACT) has been implemented for quasi-static non-linear analysis.

The definition is a master-slave type.

Frequency dependent damping element

A new frequency dependent damping element (PBUSHT) is available.

Grid participation output For acoustic analysis, it is now possible to output grid participation results (PFGRID, PFMODE, PFPANEL).

Output of flexbodies in mnf format

.mnf files are now output directly.



Enhancements

Porting The solver is now ported on Sun x86_64 platform.

MIO support for AIX MIO file caching can now be used on AIX computers.

Memory management On 64-bit platforms, RADIOSS does not impose any limitation on the allocation of RAM available on the computer. In previous versions, the maximum memory was limited to 32GB.

Quasi-static non-linear analysis

Speed improvements were made for quasi-static non-linear analysis.

The speed-up is most noticeable for models with a small number of gaps or a small contact area (where the new contact interface definition is used).

Result output for transient analysis

Result recovery and output for transient analysis is now faster.

Coordinate systems for stress, strain, and force results

For solid and shell elements, the default output coordinate system for stress, strain, and force results has been changed to be the material system, whenever defined.

For shell elements, PARAM,OMID may be used to switch between the material and elemental system for these results.

Fluid-structure interface matrix for AMLS

For acoustic analysis using the AMLS eigensolver, developed by the University of Texas, a more efficient method of calculating the fluid-structure interface matrix has been implemented.

Hyper3D 10.0 Hyper3D libraries have been upgraded to the latest version.

PENTA15 element formulation The element formulation for PENTA15 elements has been improved.

Results may differ from previous versions because of these enhancements.

XYPUNCH output Results output via the XYPEAK, XYPLOT, and XYPUNCH controls are now output in the same order



as they are specified in the input deck.

Resolved Issues

License stacking The licensing mechanism on Windows and Linux operating systems no longer stacks licenses when they should be leveled.

RAM allocation on Windows XP 32-bit

A problem on Windows XP 32-bit, where the operating system was limiting the amount of RAM available to OptiStruct to 1.4GB has been resolved. OptiStruct 10.0 can now use up to 1.9GB RAM.

General The stiffness matrix for CBUSH elements with the 2nd grid left blank is now properly transformed back to the local coordinate system from the basic coordinate system.

The rotational DOF of rigid elements can now be removed when there are mass inertial terms associated with the grid.

When the total strain energy is zero, division by zero is avoided.

Frequency response analysis The message regarding activation of inertia relief for residual vector calculation is only written to the .out file when applicable.

When the RHO field on the MAT10 bulk data entry is left blank, the derived value has been corrected.

Transient analysis For direct transient analysis, the CDAMP1 label is now output to the PUNCH format when SORT2 is the selected output order.

Component mode synthesis DMIG output now includes WTMASS scaling.

Licensing for suspend/resume On UNIX/Linux platforms an issue related to license handling when suspending/resuming a job has been resolved.

Available number of CPUs on AIX

The number of CPUs is now determined correctly for CPUs where SMT is available but disabled.

Grid point force output Output of grid point force balance table is now correct when more than one subcase with thermal loading



existed in the model.

Thermal analysis Unused QBDY1 definitions are ignored. A WARNING is written to the .out file when unused

fields are present on MAT4, MAT5, and CHBDYE cards.

An issue with heat transfer analysis, where the presence of rod elements were causing incorrect results, has been corrected.

Known Limitations

You can use these elements to model a variety of mechanical systems. With a model in hand, you can perform a comprehensive analysis using the following simulation types:

Transient Includes both kinematic and dynamic simulations. MotionSolve provides both explicit and implicit integrators



for nonstiff and stiff problems.

Static Find the static equilibrium configuration

Quasi-static Find the sequence of static equilibria under slowly varying motion or force input (quasi static means almost static.)

Linear Linearizing the nonlinear equations of motion provides two kinds of useful information: 1) eigenvalues and normal modes that tell us about stability, natural frequencies, and vibration mode shapes, and 2) linearized equations of motion that are useful for designing control systems.

General

New Features

New Modeling Elements

CONSTRAINT_MATE CONSTRAINT_MATE element is used to specify mating constraints between geometric primitives. It differs from CONSTRAINT_JOINT and CONSTRAINT_JPRIM in that it specifies more general constraints based on distance, tangency, and coincidence relations between mating geometries.

CONSTRAINT_GENERAL CONSTRAINT_GENERAL element can be used to specify arbitrary constraints in terms of time and system states.

New User Subroutines

SET_DISCRETE_INTERFACE The SET_DISCRETE_INTERFACE subroutine tells MotionSolve to call SFOSUB, VFOSUB, VTOSUB, GFOSUB, DIFSUB, or VARSUB user subroutines discretely at successful integration steps. This is important for cosimulation between MotionSolve and another solver such as Simulink.

POST_SUB The POST_SUB user subroutine is used to generate a custom output file or perform custom processing of MotionSolve results. It can be used for real-time



animation or plotting.

MESSAGE_SUB The MESSAGE_SUB subroutine is used to generate customized solver messages.

GET_STATES The GET_STATES user subroutine is used for extracting state variables in a MotionSolve model. It is meant for use only with the Post_Sub user-written subroutine to extract MotionSolve results for output to a file or further processing for real time animation and plotting.

MODSET The MODSET subroutine accesses and modifies the model data as specified in the xml solver input file. It may be called from any user-written subroutine.

GCOSUB The GCOSUB user subroutine is used in conjunction with the CONSTRAINT_GENERAL modeling element to define arbitrary constraints.

Customization capabilities Capabilities are included for broad and deep customization of MotionSolve to suit the needs of individual modeling domains such as automotive and biomechanics.

Custom functions Custom functions allow expert users to expand the set of MotionSolve functions by adding new functions. For instance, automotive users may create a function called CAMBER to compute the tire camber angle. Such functions may be used exactly like built-in functions such as DX and DM.

Custom statements Custom statements allow expert users to expand the set of MotionSolve model elements by adding new standard model elements. Such elements can be mapped to one or more built-in elements.

Custom messaging Custom messaging refers to the ability to pass MotionSolve messages directly to MESSAGE_SUB user-written subroutine. This allows users to modify standard MotionSolve messages, or append additional comments to them.

Custom results output Custom results output refers to use of POST_SUB and GET_STATES user subroutines to create customized output files. MotionSolve calls POST_SUB at every successful integration time step.



Users have access to all the same data that passed to the MotionSolve MRF file.

Custom translation rules Custom translation rules refers to the ability to modify the translation of ADAMS dataset files into MotionSolve XML files. This is done via a mapping file, which specifies rules that override the default translation rules.

Cosimulation with Simulink Cosimulation between MotionSolve and Simulink is provided in this release. It allows users to simulate Simulink subsystems acting in concert with MotionSolve multibody systems. For instance, users can now simulate the response of a MotionSolve vehicle model to a traction controller modeled in Simulink. This is accomplished by frequent data exchange between MotionSolve and Simulink during the simulation.

Other enhancements CONTROL_DIFF elements of type Implicit are now supported with FIM_D and FIM_S static solvers.

A style sheet (XSL) and schema definition (XSD) are now available on the Altair web site for the MotionSolve XML file format. XML files generated by Altair software contain a reference to the style sheet and schema. The style sheet allows MotionSolve XML files to be formatted into neat tables in a web browser. The schema definition allows certain XML editors such as Microsoft Visual Studio to check and validate the XML files during editing.



OptiStruct 10.0 Release Notes

OptiStruct is an award winning CAE technology for conceptual design synthesis and structural optimization. OptiStruct 10.0 again brings much advancement over previous versions, with emphasis in the areas of acoustic optimization, fatigue optimization, random response optimization, MBD system level optimization, and design interpretation through OSSmooth.

Optimization

New Features

Acoustic optimization A new pressure response type considers acoustic behavior in the optimization problem.

Fatigue optimization New damage and life response types allow fatigue performance to be considered in an optimization problem.

A global damage or life target can be defined on the DTPL card for topology optimization.

Random response optimization

New PSD and RMS response types allow random response performance to be considered in an optimization problem.

MBD system level optimization New MBD system level responses allow the performance of MBD system responses to be considered in an optimization run in addition to structural responses based on the Equivalent Static Load Method (ESLM). The MBD system level responses are handled through Adaptive Response Surface Method (ARSM) (see the HyperStudy online help) during the optimization process.

In addition to ARSM, the advanced approximation strategies used in MBD system level optimization allow a large number of design variables to be handled efficiently.

Thermal and Thermo-mechanical optimization

A new temperature response type enables heat transfer optimization.

Sensitivities for thermo-mechanical coupling are now calculated, allowing optimization problems involving thermo-mechanical coupling.



System identification In addition to minimizing (or maximizing) responses, and minimizing the maximum (or maximizing the minimum) of multiple responses, it is now possible to provide target values for responses as the objective function for an optimization problem. This is commonly referred to as system identification. There are two possibilities: 1. Minimize the least squares function of all

selected targeted responses. 2. Minimize the maximum (or maximize the

minimum) relative difference for all selected targeted responses.
