How do I input viscoelastic material data?

I'm looking at the first tab (Properties), and have selected "Viscoelastic" as my model type.


1)      What visco-elastic model is used? Generalized Maxwell Model? Generalized Kelvin Model? Something else?

2)      How can we use/input the master curve (in the time domain) for our material? We have our master curve in the form G(t) = G0 + G1*e^(-t/tau)…. Can we use our coefficients directly under the “Properties” tab? Are these what are referred to as the Shear Relaxation Moduli?

3)      If 2 is true (or even if not) what are the “Time Values” under the “Properties” Tab. (I’m guessing that I should use one or the other, but not both, yes?
