      Hello, 


      I have a problem with my last step in ANSYS - Solution (Solve). Geometry, Mesh is fine, but I still getting error: 
         


      Text: "An unknown error occurred during solution.  Check the Solver Output on the Solution Information object for possible causes."


      Association: "Project>Model>Static Structural>Solution"


      I already tried everything.. 


      Help me please.

      There are so many reasons for this. Can you use the Attach button to upload a Workbench Project Archive .wbpz file to your post so I can see it?

      What version of ANSYS are you using?

    • Ondrafida

      Version 19.0 . And I already tried versions 18.2 and 19.1 - same problem. And as you can see model is quite easy ...

      I solved your model on ANSYS 19.1 and it solved without a problem.  There is nothing wrong with this model.


      The issue is with your installation of ANSYS.


      Click on the Solution Information folder and select all the text (Ctrl-A) that appears in the window and copy paste into a text editor and attach that text file to your post above.

      Here is what you can see in the Solution Output file...

      The fix is simple. In Mechanical, Tools, Solve Process Settings..., Advanced...


      Set Use GPU acceleration to None then click OK.



      This is a one-time fix and should not have to be repeated again.

      Hi Peteroznewman,


      I am having an error stating that " An unknown error occurred during solution. check the Solver Output on the Solution Information object for possible causes".


      I am doing Thermal & Structural analysis on the rocket nozzle. Thermal analysis is successful but structural analysis is showing this error. I am using Ansys workbench 18.2. Can you help me through this?


      Thanks.

      Hello, 


      I have a problem in ANSYS Workbench  Solution. I have made an analysis setting as Store Output Results at last point only to solve the issue related with disk space. Now in solution, it shows following error message. 
         


      Text: "An unknown error occurred during solution.  Check the Solver Output on the Solution Information object for possible causes."


       *** ERROR ***                           CP =   29929.479   TIME= 21:420


       The program is unable to open file file.DSP.  If the suggestions in the 


       associated error messages immediately preceding and/or following this   


       error message do not help resolve the file issue, please send the data  


       leading to this operation to your technical support provider, along     


       with the I/O error code of 30 and the system error code of 32, for      


       help in determining the possible reasons as to why this file could not  


       be opened.                                                              


       NUMBER OF WARNING MESSAGES ENCOUNTERED=          1


       NUMBER OF ERROR   MESSAGES ENCOUNTERED=          1


       


       ***** PROBLEM TERMINATED BY INDICATED ERROR(S) OR BY END OF INPUT DATA *****


       


      Help me please for this problem.
