Modelling Bingham in CFX 11.0

Dirk

Hi!

I'm trying to implement a Bingham-Material by using CCL as follows:

LIBRARY: MATERIAL: MRF ANSYS Material Group = User Option = Pure Substance Thermodynamic State = Liquid

PROPERTIES:

Option = General Material

DYNAMIC VISCOSITY:

Option = Bingham

Yield Stress = 50000 [kg m^-1 s^-2]

Viscosity Consistency = 0.5 [kg m^-1 s^-1]

Minimum Shear Strain Rate = 1.0E-3 [s^-1]

Maximum Shear Strain Rate = 100 [s^-1] END

EQUATION OF STATE:

Density = 4500 [kg m^-3]

Molar Mass = 1.0 [kg kmol^-1]

Option = Value END

END END

It doesn't work and I get the following error message:

"The parameter "Option in "/LIBRARY/MATERIAL:MRF ANSYS/PROPERTIES/DYNAMIC VISCOSITY" has the value "Bingham". This does not match any of the allowed values: "Value, Sutherlands Formula, Rigid Non Interacting Sphere Model"."

As I understand this error message, the Bingham-Modell is not known by the program, but in the help it is explained in that way. Is there something wrong in my CCL-command?

I'm using ANSYS Workbench with CFX V11.0 SP1!

Hopefully someone can help me. I look forward.
