"Restarting kernel" Problem

[DavidMk]

I wrote a new steel material model for OpenSees. When I test it in cyclic pushover analysis and time history analysis in Openseespy using Spyder, it occasionally goes into "restarting kernel..." after quite a lot of steps (in the middle of the analysis). Does anyone know what would be the possible reason that cause this problem?

Use the ops.logFile command to get the output. You might see something there. Probably a memory leak or seg fault in your material model, assuming this does not happen with one of the already available material models.
