Class
    Foam::qhdFluxFvPatchScalarField

Group
    grpQGDBCs grpWallBoundaryConditions

Description
    This boundary condition sets the pressure gradient to the provided value
    such that the flux on the boundary is that specified by the velocity
    boundary condition.

Usage
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            qhdFlux;
    }
    \endverbatim
