Activation Energy for Polymer Flow Simulation

  Hello,
  
  I would like to simulate a tube flow of a polymer (viscosity depends on shear rate and Temperature). From other Simulations I am used to the WLF Temperature shift, but Fluent reuqires an Activation Energy (Maybe from the Arrhenius equation?).
  
  Does anybody know where I get this Activation Energy from?
  
  Thanks in advance!

  It'll depend on the viscosity model you want to use: what does the equation in DOC say?

  I would like to use the non-newtonian power law.
  
  What do you mean with DOC?

  DOC - documentation. The User Guides.
