Hello everybody,

i am using two subroutines "USDFLD" and "UMATH" and i use the stress from "USDFLD" as a state variable to "UMATH". After finishin "UMATH" somehow my statevariable is again 0 but i want to keep it in order to have the stresses in all my integration points. I hope somebody can help. I have attached my subroutine.

Best regards
