Hi Mehdi Shahzamanian,

Try changing Constraint enforcement method from Default to Penalty(Standard) or Augmented Lagrange(Standard) in Contact Property Options (Interaction->Property->Edit ).

Hi Dr. Adlucky,

Thank you for answering this question. I got it, however, what about using UDMGINI. Kindly let me know what is the ABAQUS command line to pick the UMAT and UDMGINI simultaneously, I tried the following command, but it didn't work;

"ABAQUS job=example.inp user=UMAT.for & UDMGINI.for"

Kindly let me know if you have any ideas in this regard. Thank you.

Regards,

Mehdi

Try including both subroutines to one .for file.

Hi again,

Thank you for your help. I tried it and it worked. Thanks!

Mehdi

hi Mehdi Shahzamanian,

how could you solve this problem? I met the same problem in combining crystal plasticity UMAT and XFEM. Any help is appreciated, thank you.

Hi Wenjie,

In fact, one must put all the codes in a single code as a subroutine and run that single file.
