Dear friends,
I am going to doing a " Liquid-Solid" simulation but the CFX software shows an error and says that the "Viscosity" should be defined for solid phase moreover in the help of software is stated that for liquid-solid simulation the viscosity should be defined for solid phase, but when I try to define viscosity for solid phase there is not the item of viscosity for solid phases, help me please.

sincerely
