I am trying to simulate a two phase vof model in which one of the phases is a polymer and the other is air. When i try to define viscosity of the polymer in the properties table with non-newtonian powerlaw model, at the end it says that
"Note: Enabling energy equation as required by material density method. " and the solver is automatically enabling energy equation which I dont want to. I just want to simulate the fluid mechanics part of the case.
Please help me what wud be the problem??

Depending on the model you choose for non-Newtonian behavior, a reference temperature is required. If a reference temperature is required, the energy equation must be enabled.
Please look at the Fluent manual (section 8.4.5) and you'll be able to see which non-Newtonian models require a reference temperature
