Class
    Foam::energyJumpFvPatchScalarField

Group
    grpThermoBoundaryConditions grpCoupledBoundaryConditions

Description
    This boundary condition provides an energy jump condition across a pair
    of coupled patches.  It is not applied directly, but is employed on-the-fly
    when converting temperature boundary conditions into energy.
