      /Hi there 

       

      I ama trying to use usercreep and usermat.f codes for the same solid body. but I can't see the creep stress for that body. Is it possible to use them as same time for a body?

      I am not aware of a documented limitation to this combination.  

      Are you including 'RATE,on' in /SOLU before executing the SOLVE?

      If yes, does your usercreep.F work as expected when usermat.F is excluded?

      the point is i want to use usercreep and usermat at the same time but only usermat workes and i can't see usercreep results there . still with RATE,on it doesn't show anything there for creep.

      I just confirmed that this combination is actually not supported. We have no good way of iterating between creep and plasticity when they are both user routines.

      Section 4.22.2 of the Material Reference Guide documents the subroutine combinations that are supported.  

      Sorry for the confusion.
