Power Law Fluid Model

Please login with a confirmed email address before reporting spam

Hello all,

I'm currently interested in using the Power Law Fluid Model for one of my simulations, however my PI does not have the resources currently to buy the "add-on" for version 4.3a.

Is there a way to have COMSOL calculate Viscosity as a function of shear rate? Heres what I've come up with so far but currently its not working.

Visc = m * (fsi.sr_fluid)^(n-1)

Where m and n are parameters of the model.

Any help is much appreciated.
