Abaqus 2018 coupled with Fortran compiler 2016 and Visual studio 2015 works good with any number of elements. But Abaqus 2020 coupled with Fortran compiler 2016 and Visual studio 2015 only works for a few number of elements.

For more than 60 elements, Analysis aborted due to the following error:

"ERROR in job messaging system: Error in connection to analysis
Error in job Job-1: Abaqus/Standard Analysis exited with an error - Please see the message file for possible error messages if the file exists."

I would appreciate any help anyone can provide.
