How to Model Non-Newtonian Fluids

Hello, I need to model some non-newtonian fluids i.e. shear-thinning, shear thickening, power law, viscoelastic etc. Can someone explain to me how I can input viscosity as a changing function, using a user defined model? Or is it better to use a built in adjustable one? If so please provide some guidance on how I can get started using either of these methods.
Thank you very much for your time.

for simple non-Newtonian fluids like shear-thinning, shear thickening and power law, you can simply change viscosity in material panel, some models exist or finally use a UDF.
but for viscoelastic materials you can't using FLUENT. for this purpose you can use POLYFLOW or OpenFOAM.
