Class
    Foam::mappedFlowRateFvPatchVectorField

Group
    grpInletBoundaryConditions grpCoupledBoundaryConditions

Description
    Describes a volumetric/mass flow normal vector boundary condition by its
    magnitude as an integral over its area.

    The inlet mass flux is taken from the neighbour region.

    The basis of the patch (volumetric or mass) is determined by the
    dimensions of the flux, phi.  The current density is used to correct the
    velocity when applying the mass basis.

Usage
    \table
        Property     | Description             | Required    | Default value
        phi          | flux field name         | no          | phi
        rho          | density field name      | no          | rho
        neigPhi      | name of flux field on neighbour mesh | yes |
    \endtable

    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            mappedFlowRate;
        phi             phi;
        rho             rho;
        neigPhi         phi;
        value           uniform (0 0 0); // placeholder
    }
    \endverbatim
