Herschel-Bulkley & Fluent 6
I notice there's a Herschel-Bulkley viscosity option in the materials panel in Fluent 6. Anyone tried it yet? I also notice you can only use the laminar viscous model with non-Newtonian viscosities. Was this the case in Fluent 5? I seem to remember you could use the K-Epsilon model with non-Newtonian fluids.

Re: Herschel-Bulkley & Fluent 6
The non-Newtonian viscosity models are not active when the viscosity model is anything other than "Laminar". You need to define a UDF for the Herschel-Buckley viscosity. Only then would you be able to activate a turbulence model.
