thank you very much for your clear explanation and help.

For one example I have Prony Shear Relaxation parameters, therefore I implemented the way that you said and everything works well for a certain temperature.

1) But for other examples I do not have Prony series parameters, therefore, I should do the curve fitting as you suggested but what option should be used for curve fitting? I could not manage to do that.

2) I want to see the behavior of the material while the temperature is changing, therefore I can define the Isotropic Elasticity behavior dependant on temperature [Fig 4]. But I don't know how to get output dependant on temperature; Is there anything that I should add at the Analysis Settings? Do you have any suggestions?
