The Fluid Properties node adds the momentum equations solved by the physics interface, except for volume forces which are added by the Volume Force feature. The node also provides an interface for defining the fluid properties of the fluid.

The default Density ρ (SI unit: kg/m3) is User defined and is 1 × 103 kg/m3.

The fluid model is selected as non-Newtonian, enter a value or expression for the more parameters like Yield stress τs (SI unit: Pa) and Plastic viscosity μs (SI unit: Pa·s).
