Ansys Workbench (SIG$ILL) error
 

Hi everyone, I'm using Ansys Workbench for a static struttural problem .
After I imported cad model, created a mesh, defined constraints and forces, finally I tried to solve, but getting the following error:
An unknown error occurred during solution. Check the Solver Output on the Solution Information object for possible causes.
After I checked the solver the following error comes up:
*** ERROR ***
"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 got the same error using 14.5 and 16 Ansys version.
Does anybody know what could be the cause for it?
