The OpenSees Community

Hello everyone,
I'm starting to use OpenSeesSP and I have got that it works using 1 core but when I apply for more than 1 core, I obtain the following:

Example for 4 cores:
........................
job aborted:
rank: node: exit code [: error message]
0: WIN-VC9M7QD7A0: 123
1: WIN-VC9M7QD7A0: 123
2: WIN-VC9M7QD7A0: -1073741819: process 2 exited without calling finalize
3: WIN-VC9M7QD7A0: 123
........................

Whot does it mean? What can I do?

Thanks in advance

I am encountering the the exact same problem. I have two different models. One of them runs fine on all threads but the other one can only run on one core?

Does anybody have an idea what might be causing such error?

Ömer.

Okay, I seemed to have found the source of my own problem. I'll write it down here just for the records.

In my model I had some SHELLMITC4 elements and they inherited LayeredShell sections. Apparently, Mumps doesn't like it. Soon as I switched to ElasticMembranePlateSection, things went back to normal.

Ömer.

thanks .. probably LayeredShellSection is not working in parallel.

can you post the section and materials commands

Please find them below:

Thank you very much, I also use LayeredShell sections.

So, is not it possible to use shellmitc4 via openseesSP?

thanks .. probably LayeredShellSection is not working in parallel.

Is this still the case? we can not use LayeredShell for parallel processing?

Make sure that your system has enough computational resources superfoamusa (CPU, memory) available to run OpenSeesSP on multiple cores. Running out of memory or exceeding CPU limits can cause crashes.
