When solving in mechanical, the following or similar SIG$SEGV errors occur intermittently.
***ERROR *** CP = 64.031 TIME= 09:52:21 An unexpected error ( SIG$SEGV ) 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.

Software & Version
*This example was taken from this version but is not necessarily limited to this version.
SIG$SEGV errors are related to software/hardware interaction issues. It could be failing hardware, corrupt OS, corrupt Ansys install and/or corrupt model. In this documented case, since model runs were successful periodically on problematic computer and fully on others, we turned to the likely cause of a corrupt Windows or Ansys install, failing hardware (RAM, Disk, etc). In this case, it was failing memory.
- Rule out a corrupt model
- See if it can run on another computer and same version of Ansys successfully.
- Rule out hardware failure
- Rule out a Corrupt OS
- Rule out corrupt Ansys Installation
