problem during linking,this error may be due to a mismatch in abaqus user subroutine arguments.
i must say,when i use a existing umat in examples of abaqus,i see this error

The error message that you are mentioning indicates that your user material subrotine does not have the correct arguments.

I recommend that you double-check your umat code.
