The Heat Source sets up the right-hand side of the continuity equation, in Equation 2-2, in terms of a heat density source. This is a monopole-like source that acts uniformly in all directions.

where αp is the (isobaric) coefficient of thermal expansion, ρ is the density, Cp is the heat capacity at constant pressure, and Qheat is the heat source.

Enter the ambient Temperature T, the default is 293.15[K].

Enter the Heat Source Qheat (SI unit: W/m3).

Enter the Heat capacity at constant pressure Cp and the Ratio of specific heats γ either selected From material or User defined. The ratio of specific heats is used to calculate the coefficient of thermal expansion through the thermodynamic relation
