I've found these two files:
cortex error which says: " Error [cortex] [time 4/17/23 17:36:40] Cortex received a fatal signal (SEGMENTATION VIOLATION). "
fluent-999999-error which states: " Error [node 999999] [time 4/17/23 17:36:36] Abnormal Exit! "
In addittion I can't continue the computation it seems like it is finisched but it was only at 12% and it took 2 days.
