Add a Domain Sources node to define the mass source, and momentum and energy source types. This domain feature adds the right-hand side
Sc , Sm, and
Se to the governing
Equation 5-1 defined through different options
where M is a mass source, A is an acceleration source,
F is a volume force source,
prc is a pressure rate of change source, and
Q is a volumetric heat source. Notice that the mass source term enters both the momentum and the energy equations in a consistent way. The
Domain Sources can be used to create any user defined source by entering expressions into the fields. The sources can for example be point-like Gaussian sources to model an idealized single vortex or two interacting vortices.
Select a Momentum source type:
Acceleration (the default) or
Volume force. For
Acceleration enter vector expressions or values for the
Acceleration source A (SI unit: m/s
2). For
Volume force enter vector expressions or values for the
Volume force source F (SI unit: N/m
3).
Select an Energy source type:
Pressure rate of change (the default) or
Heat source. For
Pressure rate of change enter an expression or value for the
Pressure rate of change source prc (SI unit: Pa/s). For
Heat source enter vector expressions or values for the
Heat source Q (SI unit: W/m
3).
