How to fix Solver error 4031 contact marc analyst

I am running a script from cmd in Marc 2019 and after aproximately 15 minutes the simulation stops running. It does not complete a single increment and there is no exit number. The only thing I could reach to see, is a message at the end of .log file which says "Solver error 4031 contact Marc analyst".

Can anyone help me with that?

Thank you very much in advance!

Hi Aurea,

The most common reason for exit 4031 is insufficient memory. Try running on multiple cores, with PARDISO solver and see if helps. Also, if possible run it on another machine with more resources. If the issue persists, an input file would be needed to investigate further.
