Hello all,

I'm running a set of quasi-static pushover/cyclic test on a shear wall assembly using explicit. My issue is that sometimes the analysis would abort suddenly and report the following error:

ERROR in job messaging system: Error in connection to analysis

Error in job Base_Beam: Abaqus/Explicit Analysis exited with an error - Please see the status file for possible error messages if the file exists.

Job Base_Beam aborted due to errors.

I rechecked the .sta and .msg file and the following message was reported in the status file:

***ERROR: Process terminated by external request (SIGTERM or SIGINT received).

If I'm not mistaken, this message appears when the user manually terminates the job (through the GUI or command window); however I didn't do that as I left the simulation overnight hoping it would be complete by the time I wake up and to my surprise I found this error message in the morning.

I re-ran the same analysis and it worked fine, however I recently ran into the same error and I'm wondering if anyone has any explanation to what is causing ABAQUS to abort midway? I'm running the job on 6 cores using double precision on ABAQUS 2021 for anyone who's wondering.

Any help is appreciated,I can't afford having jobs abort randomly as I have a ton of jobs to run and each job takes around 14 hours to complete.

Thanks!
