Question

stress_solid_nlm.cxx and ENG_StackMemory.cxx fatal error

I am using Creo Simulate Release N/A and DatecodeN/A Running Creo Simulate version 10.0.10.0. I´m running a non-lineal simulation with contacts with linear material. Loads are only prescribed displacements. Model check shows no issues. Run without issues unload and 2 steps, then fail. Attached message. Model has 116259 elements and 10 contacts. SOLRAM 8GB (RAM 32 GB). Here are the errors that I faced *** A fatal error has occurred. *** An internal error has occurred in file z:\s\q10\sim\engine\src\as\post\stress_solid_nlm.cxx, line 166. Several times same message. An internal engine error has occurred.  Please be sure to run error checking before you run this study.  If you have run error checking, then contact Customer Support. *** A fatal error has occurred. *** An internal error has occurred in file z:\s\q10\sim\engine\src\common\utility\ENG_StackMemory.cxx, line 108

Hi ​@LM_8712221,

 

The two internal errors you listed are explaining lines within the internal Creo Simulate code so the community may not be able to provide a meaningful response beyond interpreting the file names.  As also noted in the text from your post, contacting PTC Technical support is recommended.

Hope this helps guide you in future actions related to this failed analysis,

Mike
