Class
    Foam::outletMappedUniformInletHeatAdditionFvPatchField

Group
    grpInletBoundaryConditions

Description

    This temperature boundary condition averages the temperature over the
    "outlet" patch specified by name "outletPatchName" and applies an extra
    heat source. This is set as a uniform temperature value on this patch.
    Additionally TMin/TMax limits can be applied

    \heading Patch usage

    \table
        Property    | Description             | Required    | Default value
        outletPatch | name of outlet patch    | yes         |
        Q           | Heat addition           | yes
        phi         | flux field name         | no          | phi
        TMin        | min temperature limit   | no          | 0.0
        TMax        | max temperature limit   | no          | 5000.0
    \endtable

    Example of the boundary condition specification:
    \verbatim
    myPatch
    {
        type            outletMappedUniformInletHeatAddition;
        outletPatch     aPatch;
        Q               10;     // Heat addition in W
        phi             phi;
        value           uniform 0;
    }
    \endverbatim
