@Xiaoxuan Ma,

A quick google search for this error: SIGSEGV could indicate a hardware issue. Check your hardware (run diagnostics on your RAM, MOBO, CPU). Ensure that you disable any power saving features on your Ubuntu machine. If you are running a large/complex simulation that takes a long time to run:

• Run using a different MPI framework, e.g. Open MPI or use "Local Computer" as the 'Job launching preset'. 
• Check/change your simulation to lower the run time. Or run the simulation on a machine with more processes/cores. 
• i.e.  HPC (on-premise cluster), or Ansys Cloud Direct, or Ansys Gateway powered by AWS with more processes/cores. 
• Additional licenses will be required to run on more than 32 processes/cores.
