I'm trying to simulate 3D blood flow using Casson model as Dynamic Viscosity. I created a material in CFX-Pre and entered data previously suggested by Opaque. Here are the details when I open the material in command editor:
LIBRARY: MATERIAL: Casson
Material Group = User
Object Origin = User
Option = Pure Substance
Option = General Material
Maximum Shear Strain Rate = 100 [s^-1]
Minimum Shear Strain Rate = 0.001 [s^-1]
Option = Casson
Viscosity Consistency = 10 [kg m^-1 s^-1.0]
Yield Stress = 100 [Pa]
EQUATION OF STATE:
Density = 1050 [kg m^-3]
Molar Mass = 1e-10 [kg kmol^-1]
Option = Value
END END END
CFX is giving me the following error: "The parameter "Option in "/LIBRARY/MATERIAL:Casson/PROPERTIES/DYNAMIC VISCOSITY" has the value "Casson". This does not match any of the allowed values: "Value, Sutherlands Formula, Rigid Non Interacting Sphere Model".
Can anyone help with this?

Re: CEL error
Are you using ANSYS CFX 11.0? If you are, please write the definition file and see what the solver does.
The "generalized non-newtonian models" are not allowed in the GUI (beta hidden capability), but they should work in the solver.
Keep us posted, Opaque
