Hi @andraderenew,
Check this other thread reporting the same error, it seem related to memory:
It could be found with the error code showed in the shared error message:
** OpenMEEG error #137:
https://neuroimage.usc.edu/forums/t/openmeeg-error-137/10939
To avoid duplicating posts, please post on that other thread if you issue has the same cause.
Use the monitor system software in Ubuntu to track the usage of RAM to see if that is the case
