Principal Stresses in Usercreep.F

Principal Stresses in Usercreep.F

(OP)
Hello,

I am trying to implement a user defined creep model in ANSYS. Is there some way I can get the principal stresses of some element in Usercreep.F? The principal stresses are an input to my model and I'm not sure how to retrieve them. The example only shows hydrostatic and equivalent stress being available.

Any help would be greatly appreciated!

This link shows the inputs: http://www.cadfamily.com/download-pd..._USERCREEP.... on page 9 of the slide. I see that 'pres' and 'seqv' are inputs to the usercreep function. Can I just modify the input function to add a principal stress vector?
