Hi, at first thanks for your help:*
I run a multiphase flow, continuous liquid(water) with dispersed solid(copper).
in pre setup, this message appear:
In Analysis 'Flow Analysis 1' - Domain 'Domain 1': The following materials require Viscosity to be defined: 'Copper'
but there is no box in material section to define viscosity, what do you think?
thanks alot

ya.. same here as well...another problem is

In Analysis 'Flow Analysis 1' - Domain 'fluid': The use of the 'Liquid Evaporation Model' in the component pair 'H2O | Water' requires the existence of a Homogeneous Binary Mixture that defines the Antoine coefficients.

.i already create the homogeneous binary mixture material.. but where to insert it to the fluid domain ????? thanks....

Can you both please take a screen print of your Domain>Basic Settings?

You would have to manually define a very small insignificant molecular viscosity of copper.
Click on material tab on top menu, and define a new material and name it "copper1". Use the following options,

Basic Settings>Option> Pure Substance
>Material Group>User

Define all the material properties as in predefined "Copper", you can now define viscosity as well in
Material Properties>Transport Properties>Dynamic Viscosity.
