Hello!Thanks for your reply.

Yes, I run the subroutine successfully without error before I add the fifth state variable. The successful subroutine"usercreep" is based on Anand model.And I want to add "backstress" into Anand model,please give me some suggestions.Can I add the backstress concept to the usercreep user subroutine?By the way,When the APDL program reports another error, I click proceed and the program exits. And I view the file.err, there is only "SIG$SEGV" error. How do I check the value of the status variable?This is important for me. Thanks again!
