Carreau model option not appearing

up201506004

Hello,

I am following the tutorial 3D Bifurcating Artery, and to create the material blood, which is non-newtonian, the Carreau model is used to model the viscosity. However, I do not have that option.

I am using ANSYS R2 2020 Student version.

I do not want to write the Carreau model as an expression, but if there is no choice, how do I write the shear rate variable and H(T) in the expression?

Thanks in advance.

Hello,

Carreau model is not available for turbulent flows. Please check if you are able to see it when you turn on the Laminar flow.

Thank you for answering.

The viscosity was not laminar for some reason.

Now the option is there.

Thank you very much for all the help.

Hello,

Please go to Viscous Model -> (and select) Laminar. The viscous model is set to the Turbulent model by default.

I followed your instructions still I can't seem to find the carreau model.

Hello,

Pick the Laminar model and then you should find the option under Viscosity (fluid properties). Which version are you using?
