Class
    Foam::gradientEnergyFvPatchScalarField

Description
    This boundary condition provides a gradient condition for energy. This is
    selected when the corresponding temperature condition is zeroGradient,
    fixedGradient or gradientEnergyCalculatedTemperature.

    If the temperature condition is fixedGradient or zeroGradient, the
    parameters of the energy condition are obtained from a linearisation of the
    corresponding parameters of the temperature condition.

    If the temperature condition is gradientEnergyCalculatedTemperature, then
    the temperature condition explicitly provides an energy gradient field, so
    no linearisation is needed.
