Class
    Foam::wallHeatTransferFvPatchScalarField

Group
    grpThermoBoundaryConditions grpWallBoundaryConditions

Description
    This boundary condition provides an enthalpy condition for wall heat
    transfer

Usage
    \table
        Property     | Description             | Required    | Default value
        Tinf         | wall temperature        | yes         |
        alphaWall    | thermal diffusivity     | yes         |
    \endtable

    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            wallHeatTransfer;
        Tinf            uniform 500;
        alphaWall       uniform 1;
    }
