solid particle dynamic viscosity
 

hi
question 1:
I want to model a mixture of solid particle and a non-Newtonian fluid.
First the materials must be defined.
when I want to define a new material for solid particle, I have problem with dynamic viscosity. It has 3 model. 1-Value 2-kinetic theory model 3- non Newtonian model. what model should I choose? If I choose "Value", What value should I enter. I haven't any value for solid particle dynamic viscosity.
in material properties tab----> transport properties--->dynamic viscosity
------------------------------------------------------------
question 2:
In defining non Newtonian fluid. I choose "bingham" model.
but I don't have any value for "Min shear strain rate", "Max shear strain rate" and "viscosity consistency". what should I do?
