Hello everyone,

I am trying to use an analytic function to define a material property. The function is Carreau_Yasuda fluid model which is basically the viscosity as fuction of shear rate. My question is how to define the shear rate as a variable for a 3D problem in COMSOL. The equations are attached.


Thank you very much,
Alhasan.
