Hi, everytime I try to solve mechanical APDL, it crashes. In the .err file I saw the following:

 *** ERROR ***                          CP =     32.859  TIME= 23:12:00

An unexpected error ( SIG$ILL ) has occurred... ANSYS internal data   

 has been corrupted. ANSYS is unable to recover and will terminate.    

 Previously saved files are unaffected. Please send the data leading   

 to this operation to your technical support provider, as this will

 allow ANSYS, Inc to improve the program.                               

I have already looked through Google search and this forum but none of the threads gave a solution that worked. Note that the .ans file I ran works on another pc just fine. Information about my pc:

Windows 10 64 Bit

CPU AMD FX-8320

RAM 16 GB DDR3

GPU Nvidia GeForce 760

Windows and all drivers are up-to-date. Many of the solutions in other threads mentioned that "distributed solution" should be turned off in the process solver options. However, I am using APDL and I can't seem this option. I did see some options in the APDL launcher under "High Performance Computing Setup", where I tried all sorts of combinations but none of them worked.

Any help would be greatly appreciated!

Hi,
Is this error message reproducible to only this model or any other model as well?
Could you please run the model inthelatest available release of ANSYS ifyou havenot already doneso?
I can suggest few things you can try.
1)Try to remove the complexities as much you can.
2)Then try to run the model, Once the model runs fine then you can slowly move toward the goal.
3)This will help you in identifying the root-cause or functionality which causes this error.
Thanks
Manish

Please tell us the Ansys version you are using.
And, does this happen on all models on that particular machine?

My guess is that you are using a fairly new version of Ansys Mechanical....correct? The newer versions will use the AMD Blas library (basic linear algebra subsystems) but older AMD cpus do not support this (it's fairly new). Does this only happen when solving one type of physics? For example when solving modal analyses but static structural runs fine. If so try putting "-blas intel" on the MAPDL command line to use the Intel Blas library. If using WB Mechanical then in the solve process settings; the specific solve process click the Advanced button; in the Advanced set up there is a place to add command line arguments. Add that without the quote marks and let us know what happens.

I had the same error running a static structural anaysis using version 2022 r1 , this solved my problem , thank you.
