Viscous Heating of PEEK in Ansys

Hi, Im making a research related to viscous heating of the PEEK, but Im really new on the polymer topic and when I went to ansys I really dont know how to introduce the parameters needed on the program. So far I have G,G as a function of Frecuency and Temperature. Im not sure if I must put something like the Prony series or something else to add some viscoelastic properties on the simulation. Any advice or book review will be appreciated.

If you specify a linear viscoelastic model (a Prony series), then you should be able to predict viscous heating.
Note that linear viscoelasticity will only be suitable if the strains are very small.
