I want to create a simulation in which the viscosity of the material varies with time and temperature, by this I mean if you place this material on a plate at constant temperature,over time its viscosity will change. The viscosity of the material will initial decrease and then after time t it will start increasing at an exponential rate.

I would like to simulate this for varying geometries, temperatures and materials. Is this even possible to simulate using CFD or does it require a different simulation type? If possible using CFD could anyone give me any guidance on what I need to understand before attempting something like this?
