The outletMappedUniformInletHeatAddition is a boundary condition that provides a 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.


The condition requires entries in both the boundary and field files.

Boundary file

    type            patch;

Field file

    // Mandatory entries
    type            outletMappedUniformInletHeatAddition;
    outletPatch     <word>;
    Q               <scalar>;

    // Optional entries
    phi             <word>;
    TMin            <scalar>;
    TMax            <scalar>;

    // Inherited entries
