Ansys Employee

I see you are using a very old version 16.0 which is not supported officially by us. Is it possible to try a newer version?

Also, it looks like some data is corrupted in the project as per the message. Have you tried running a simple project?

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.                


You can try renaming the %appdata%\Ansys folder to %appdata%\Ansys.old and then retry again.
