You will now specify the fluid properties, using the Material data menu item.
Material data
For this problem, you will define only the viscosity of the material. Select Shear-rate dependence of viscosity, and then choose the Cross law. You will need to specify three parameters for the Cross law: , , and . See Cross Law for details about the Cross Law and its applicability.

Check that the values of the constants are correct at the top of the Cross law menu, and repeat the previous steps if you need to modify the constants again. Then click Upper level menu three times to complete the material data specification. Ansys Polydata will highlight the Flow boundary conditions menu item for you.
