Use the Heat Transfer node to define the density, yield stress, plastic viscosity, and heat convection and conduction properties.

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

Enter a value or expression for the Yield stress τs (SI unit: Pa) and Plastic viscosity μs (SI unit: Pa·s). The defaults are 0 Pa and 0 Pa·s, respectively.

The default Heat capacity at constant pressure Cp (SI unit: J/(kg·K)), Ratio of specific heats γ (dimensionless), and Thermal conductivity k (SI unit: W/(m·K)) all use values From material. For User defined enter different values or expressions.
