Hi Ben Armitage

What operating system and cpu does your compute system have?  The "ILL" on SIG$ILL is illegal operation.  So the CPU/OS does not understand some command sent to it.  And "SEGV" is segment violation meaning there was garbage in the memory location that something tried to access.  I have a few guesses on what is happening but I'll wait on your answers (including which version of WB Mechanical is being used).  Mike
