Aborting: mpiexec on DESKTOP failed to communicate with smpd manager on DESKTOP

Hello All,

I am performing a dynamic explicit analysis with Abaqus21, and it is getting aborted after 12-13 hrs. From Log file I got the below error mesg.

Aborting: mpiexec on DESKTOP failed to communicate with smpd manager on DESKTOP

Please note, I am using my local machine for the analysis.

Does anyone have any idea why this is happening? How to rectify this?

Thanks

K.B
