Hello,

Recently I updated my Abaqus Fortran compiler with the intel oneAPI, however find the umat crystal plasticity code doesn't work. I have already added the !DEC$ ATTRIBUTES ALIAS:"umat"::UMAT line in the begining. However, in log file, it just says:

Error in job copper_cube_101_test1: Abaqus/Standard Analysis exited with an error - Please see the message file for possible error messages if the file exists.
Job copper_cube_101_test1 aborted due to errors.

The problem is, there isn't any msg files output. I have also attached the files necessary to reproduce this, could anyone help me?
