Detailed Description

Evolves a simplified energy transport equation for incompressible flows. It takes into account the inertia, conduction and convection terms plus a source.

- The field name must be temperature and its BC's specified in the time directory.

  • The turbulence model should be incompressible
  • In order to use in a incompressible multi phase a list of thermal properties are needed. See below
