HyperForm, a subset of Manufacturing Solutions, is a finite element based pre- and post-processor for sheet

metal forming. It combines an extremely fast one-step solver and incremental forming solution using Radioss

as the solver. It also integrates well with the LS-DYNA solver for incremental forming simulation. With the

customized geometry manipulation and mesh generation capabilities, HyperForm enables you to build metalforming related finite element models, view their results, and perform data analysis.

HyperForm integrates the functionality of HyperMesh and provides engineers at any stage of product design

with quick, valuable, reliable information, reducing the overall product cyc le. HyperForm's die module enables

engineers to create and analyze conceptual die designs in order to generate an optimized die. Die concepts

can then be read into any CAD system as a starting block for the actual die build. Integrated with HyperView,

HyperForm can export data in the .h3dformat allowing results to be visualized using HyperView Player with

any web browser.

This tutorial introduces HyperForm, as well as many basic concepts and tasks that are needed to get started

with HyperForm, and which serve as pre-requisites for most other HyperForm tutorials. In this tutorial, you

will be introduced to HyperForm from the one-step analysis point of view. The HyperForm interface for

incremental analysis will be described in later tutorials.

Session 4: The concept of a collector

Collectors store entities, grouping together all the data pertaining to an entity and allowing you to handle the

data as a group. Collectors in HyperForm consist of the Components, Materials and Sections (for

Incremental_Radioss and Incremental_LsDyna analysis) panels.

The component and material collectors in HyperForm have specific data associated with them. In one-step

analysis, the component collector contains thickness data while the material collector holds the YoungsModulus of Elasticity value and other constants.

All entit ies in a HyperForm database are stored in collectors. Based on the analysis type, each collector

may use a dictionary or card image to define the attributes assigned to the collector.

The Collectorspanel allows you to create and update collectors and assign and edit card images or

dictionaries. Before you build a model, create a component collector for storingor organizing different data.

Exercise 2: Understanding collectors and using online help

The Die_Mesh.hmfile from Exercise 1 should still be loaded in HyperForm.

In steps 1 through 6, you will practice changing the visualization of component collectors.

1. In the Model Browser, click on the Mesh icon next to the Partcomponent to turn off the display of

the mesh for that component. Notice the mesh of the Partcomponent is no longer displayed in the

graphics area. The surface of the Partcomponent is still visible.

Session 6: Default HyperForm Files

HyperForm includes or automatically creates several default files. These include:

hm.cfg configuration file

hmmenu.set user interface settings

command.

cmf

command file

hm.cfg

The hm.cfgfile is a default configuration file read on start-up. The hm.cfgfile controls many aspects of

how HyperForm runs at your particular site. You can edit the commands in the hm.cfgfile to your own

preferences.

command.cmf

The command.cmffile is a standard ASCII file that HyperForm reads and writes. Command files allow you

to retrieve a work session in case of a system crash or program a series of procedures. You can use a

command file in applications that contain repetitive steps or you can create demonstrations.

All commands executed by the HyperForm command processor are written to this file. This file is


36/374



automatically created in the directory in which you started HyperForm. If the file already exists, new

commands are appended to the existing file.

For more information about the command.cmffile, please see the HyperForm online help topic HyperForm

Commands.

hmmenu.set

Thehmmenu.setfile is a binary file that HyperForm updates when you exit HyperForm. Your personal

hmmenu.setfile stores many global parameters and is located in the directory from which you started

HyperForm. If the file already exists, it is overwritten after you run a new session. The most recent global

parameter values in the current HyperForm session are written to this file when you exit. The next time you

start HyperForm, it has the values recorded in the hmmenu.setfile. If the file does not exist when

HyperForm is invoked, the global parameter values are default values.

Step 3: Setting the stamping direction


44/374



1. Right click on Stamp ing Direct ion:X and select Z.

Note: Stamping can also be done in any of the three principal axes or an arbitrary axis in space by

using Stamping Directionin the Autotip panel. Use the stamping directionsubpanel to specify the

stamping in an arbitrary direction.

In the Autotippanel, use the vector selector switch to assign a direction. If the stamping direction of

the part is not one of the principal axes, use N1, N2, N3 option and select 2 nodes on the model to

define a direction.

Click set.

Step 4: Selecting the blankholder

Blankholders can be defined as the upper and lower holding surfaces that control metal flow around a shape

to be formed in a draw operation. They supply a restraining force on the material during the pressing

process.

HyperForm allows you to define the blankholder force in two ways: on element and on edge. The correlation

between the magnitude and level of the applied forces is always available. Edge blankholder force applicationallows you to restrain an edge by enabling automatic selection of all nodes between two user-defined nodes

along a free edge of a part.

You can define the blankholder force in two ways: tonnage force or pressure level (high, medium and low).

Note The pressure level is proportional to the area of blank under the blankholder as well as thickness.

A pressure level of 2MPa, 5MPa and 10MPa for a 1mm blank has been chosen as a reference for

Low, Medium, and High (based on practical experience). The tonnage (metric ton unit) is equivalent

to the pressure times the blankholder area normalized/scaled by the thickness (1 metric ton =

9810N).

1. In the OneSteptab, right click on Blankhol ders >New. If desired, you can double click on

Blankholder1 to change the name.

2. Right click on Blankho lder1 >Elements

3. Click elemsand select on plane.

Fr ict ion and Tonnage to change the values.

7. Right click on Pressur e Level: and select Med ium.

Notice that the Tonnagechanges according to the selected pressure level.

Step 5: Creating drawbeads

Modeling the exact drawbead geometry requires a large number of elements, which increases CPU time

dramatically. A practical approach is to use an equivalent drawbead model by representing the drawbead

analytically and providing a constant drawbead restraining force and closure force.


45/374



Use the calculatesubpanel to determine the closure and restraining force based on drawbead dimensions.

The restraining force is the value of the force (per unit length) applied by the bead in the plane of the blank

surface. The closure force is the force (per unit length) required in the perpendicular direction to keep the

drawbead closed.

1. From the OneSteptab, right-click on Drawbeads > New >Restrain.

2. Pick two nodes on the part as indicated in the image below to define the drawbeads.

3. Click create.

Notice a message shows "The drawbead set has been created." A line representing drawbeads iscreated.

4. Notice that Drawbead1is created with a default Restraint Force and Pressure Level. Double click

Drawbead1 to rename it.

When designers create CAD geometry, their priorities are different from those of analysts trying to use the

data. A single smooth surface is typically split into smaller patches, each a separate mathematical face.

The juncture between two surfaces often contains gaps, overlaps, or other misalignments.

To make the geometry more appropriate for meshing, analysts need to combine a number of faces into a

single smooth surface. A single, smooth surface not only allows the elements to be created on the entire

region at once, but also prevents unnecessary artificial or accidental edges from being present in the final

mesh.

Sometimes, the gaps, overlaps, and misalignments present when surface data is imported can affect the

mesh quality. By eliminating misalignments and holes, and suppressing boundaries between adjacent

surfaces and unnecessary details, you can automesh across larger, more logical regions of the model and

improve the overall meshing speed and quality.

In this tutorial, you will use a variety of tools to prepare surface geometry for meshing.

The Auto Cleanup panel performs automatic geometry cleanup

Quick Editpanel (F11 hotkey)

This panel combines many tools for rapid editing of model geometry.

Exercise 1: Reviewing geometric problems

In this exercise, you will first review a variety of common geometric problems after reading a CAD file. The


54/374



solutions are discussed in Exercise 2.

This exercise uses the model file Bpillar_cleanup.hf.


1. Click File >Open....

2. Browse to the location \tutorials\mfs\hf\1Stepand select the

Bpillar_cleanup.hffile.

3. Click Open.

Step 2: Review the model in Topology color mode

1. Click View >Toolbars> Visualizat ionto display the Visualization toolbar. The Visualization toolbar will

need the panels displayed also in the Viewmenu.

2. From the toolbar, select Geom etry Color M ode and change to By Topo.

Notice the color of the model is changed and topology definitions are displayed on screen.

3. From the toolbar, click Shaded Geom etry & Surface Edges icon to shade the surfaces on screen.

The model comes in with several geometric problems after importing. You will first review the problems to

have a better understanding of the nature of the model.

In Topologycolor mode, each colorrepresents different topological modes:

Free edge(Red color): The edge is owned by one surface. On a clean model, free edges appear only

along the outer perimeter of the part and internal holes. Free edges that appear between two adjacent

surfaces indicate the existence of a gap between the two surfaces.

Shared edge(Green color): The edge is owned by two adjacent surfaces. When the edges between

two adjacent surfaces are shared (green), there is no gap or overlap between the two surfaces, and they

are geometrically continuous. The automesh utility always places seed nodes along their length and will


55/374



produce a continuous mesh without any gaps along that edge. The automesh utility will not construct

any individual elements that cross over a shared edge.

Suppressed edge(Blue color): The edge is owned and shared by two adjacent surfaces but it is ignored

by the automesh utility. They are blue dotted lines by default. Like a shared edge, a suppressed edge

indicates geometric continuity between two surfaces but, unlike a shared edge, the automesh utility will

mesh across a suppressed edge as if were not even there. The automesh utility does not place seednodes along their length and, consequently, individual elements will span across it. By suppressing

undesirable edges you are effectively combining surfaces into larger logical meshable regions.

Non-manifold edge(Yellow color): The edge is owned by three or more surfaces. They typically occur

at "T" intersections between surfaces or when 2 or more duplicate surfaces exist. The automesh utility

always places seed nodes along their length and will produce a continuous mesh without any gaps along

that edge. The automesh utility will not construct any individual elements that cross over a nonmanifold

edge. These edges cannot be suppressed and can sometimes be indication for duplicated geometry.

Step 3: Review and measure the largest pinhole diameter

1. From the toolbar, select the Visualizat ionicon .

2. From the Visualizationtab, select the Topo logyicon and clear the Shared, Suppressedand
