Ensure that the ANSYS product and Workbench project files are accessible on the local machine, or on a mapped drive.  http:\/\/support.microsoft.com\/kb\/978856 http:\/\/support.microsoft.com\/kb\/156276  Filename limits may also be a factor. Use a mapped drive to avoid the filename length limits.  http:\/\/msdn.microsoft.com\/en-us\/library\/Aa365247  This error has also been seen after an incomplete installation. Some antivirus programs can prevent certain library files from installing. In such cases it has been observed that the folder C:Program FilesANSYS Incv1xxansysbinwinx64 is missing a number of dll files. That folder should contain dozens of dlls. If it does not, then it may be necessary to uninstall, turn off antivirus, repeat the installation and then turn on antivirus.  Additional sources of error are described in Help, see section  \/\/ Mechanical User Guide \/\/ Troubleshooting :: 4 \/\/ Problem Situations :: 0 \/\/ An Error Occurred While Starting the Solver Module  To get further information on what the issue may be, insert a Solution Information object under Solution in the tree, and view the contents. Possible reasons that the solver may fail are:  1. Insufficient memory &#8211; You may not have enough virtual memory assigned to your system. To increase the allocation of virtual memory (total paging file size), go to Settings> Control Panel> System (on your Windows Start Menu). Click the Advanced tab and then click Performance Options. Increase the size of your virtual memory.  2. Insufficient disk space &#8211; You may not have enough disk space to support the increase in virtual memory and the temporary files that are created in the analysis. Be sure you have enough disk space or move to an area where you have enough.  3. Corrupt product installation  4. License request rejected  5. The startup directory for cmd.exe has been overridden by the AUTORUN option and as a result causes the solver to be unable to locate the solver input files.<\/p>\n","protected":false},"template":"","class_list":["post-162019","topic","type-topic","status-publish","hentry","topic-tag-4457","topic-tag-installation-licensing-systems","topic-tag-mechanical-f-simulation","topic-tag-startup","topic-tag-systems-installation"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 4.9.10 - aioseo.com -->\n\t<meta name=\"description\" content=\"This error can occur when the ANSYS product or Workbench project files are located on an external device, or on a network drive using a UNC path.
