The following information is relevant to ANSYS Release 14.5.7 and serves as anupdate to the entries published in the ANSYS Inc. Known Issues and Limitations

document for Release 14.5.

Important

ANSYS Release 14.5 must first be manually uninstalled before in-stalling Release 14.5.7. Detailed instructions to uninstall the productare available via the ANSYS Customer Portal at Downloads> Installationand Licensing Help and Tutorials. In the Installation and LicensingBasics section of the customer portal page, open the Installation andLicensing Documentation PDF. Within either the ANSYS, Inc. Installation

If you have any problems installing this program, please contact your IT depart-ment.

Windows Installation Instructions

Be aware that Windows 7, 8, and Vista use a feature called User Account Control(UAC) to control privileges and automatically reduce the potential of securitybreaches in the operating system. However, UAC limits your accessibility to systemareas and can cause unpredictable behavior in ANSYS products. Because of thislimitation, we strongly recommend performing the installation with full adminis-trative options.



Recommended Installation:

• UAC should be turned off and installation performed with full administrative priv-ileges (using Run as Administrator from the context menu). Please follow your op-erating system instructions for disabling UAC. Note: Because of UAC changes inWindows 8, the recommended installation option differs from what is containedin the ANSYS, Inc. Installation Guide for Windows. Please use the recommended in-stallation procedure contained in this document when installing on Windows 8.

Detailed installation instructions for Windows are available via the ANSYS Cus-tomer Portal at Downloads> Installation and Licensing Help and Tutorials. In theInstallation and Licensing Basics section of the customer portal page, open theInstallation and Licensing Documentation PDF. Within ANSYS, Inc. InstallationGuide for Windows, see chapter 2: Platform Details and chapter 4: Installing theSoftware.

Except as described in this document, the installation steps contained in thecurrent ANSYS, Inc. Installation Guide for Windows are the same for Windows 8.

Installation

Chapter 4: Licensing



4.1. Resolved Issues and Limitations

The ANSYS 14.5 LM1 License Manager is required if you are running the Mech-anical APDL solver in the foreground from within the Release 14.5.7 ANSYSMechanical application. Using the Release 14.5 ANSYS License Manager (withoutLM1) will result in the error message:

Capability 10209 has not been configured.If you encounter this error message, please upgrade the ANSYS License Managerto 14.5 LM1. (55141)

At Release 14.5, the strings displayed during the installation's licensing configur-ation process and in the ANSLIC_ADMIN utility were only available in English.The required changes have been made so these strings will now show correctlyfor other supported languages. (55253)

9.1. CAD Connections & Integration

Since Release 14.5, the following CAD packages have updated versions (notedbelow) supported for Release 14.5.7:

• CatiaV5–CAD Nexus CAPRI CAE Gateway (V5–6R2012)

• Solid Edge ST5

• SolidWorks 2013

• NX 8.5

A complete listing of the Release 14.5.7 supported platforms (Workbench-hostedCAD Interfaces) is available on the ANSYS Website (www.ansys.com). Go toSupport> Platform Support.




Text attribute handling in the NX plug-in on Linux systems is now correctlyprocessed. (30427)

A crash seen when attempting to save in Teamcenter has been corrected. (45985)

A fix was found to correct geometry refresh from Pro/Engineer when updatinga pattern quantity. (54603)

Teamcenter 2-tier and 4-tier are supported but DesignModeler crashes if thegeometry is refreshed when the geometry is not active. (53380)

In some cases the installer is unable to validate Creo Parametric 2.0 installations.When encountering this situation the remedy is to select "Skip this step forWorkbench and configure later" and/or "Skip this step for ICEM CFD and configurelater", as applies to your install options, and proceed with the installation. Uponcompletion of the installation run CAD Configuration Manager to configure CreoParametric. (56121)

When an incorrect user name and password is used to check-in an ANSYS projectinto Teamcenter 2-tier configuration, the plugin incorrectly reports that theprocess is completed successfully. Work-around: Try again with the correct username and password. The incorrect message does not appear for 4-tier configur-ation. (56673)

Please type a new item revision, instead of choosing from the item revision dropdown box while saving the project into Teamcenter. This limitation applies onlyto a new item revision, but not to the revisions of the NX geometries importedfrom Teamcenter. (56853)

Restarting the CAD Configuration Manager (CCM) loads the wrong path for theCreo Parametric 2.0 executable. (56915)
