Any scalar equation may have a source term . This covers the energy, Additional Variable, turbulence, and mass fraction equations.

A linearization coefficient

| (1–190)

may also be specified to provide robust convergence when sources are present. For the energy equation, the derivative is actually taken with respect to temperature.

For details, see General Sources in the CFX-Solver Modeling Guide.
