Application
    chtMultiRegionTwoPhaseEulerFoam

Group
    grpHeatTransferSolvers

Description
    Transient solver for buoyant, turbulent fluid flow and solid heat
    conduction with conjugate heat transfer between solid and fluid regions.

    It solves a two-phase Euler approach on the fluid region.
