Class
    Foam::prghTotalHydrostaticPressureFvPatchScalarField
 
Description
    This boundary condition provides static pressure condition for p_rgh,
    calculated as:
 
        \f[
            p_rgh = ph_rgh - 0.5 \rho |U|^2
        \f]
 
    where
    \vartable
        p_rgh   | Pressure - \rho g.(h - hRef) [Pa]
        ph_rgh  | Hydrostatic pressure - \rho g.(h - hRef) [Pa]
        h       | Height in the opposite direction to gravity
        hRef    | Reference height in the opposite direction to gravity
        \rho    | Density
        g       | Acceleration due to gravity [m/s^2]
    \endtable
 
Usage
    \table
        Property     | Description             | Required    | Default value
        U            | Velocity field name     | no          | U
        phi          | Flux field name         | no          | phi
        rho          | Density field name      | no          | rho
        ph_rgh       | ph_rgh field name       | no          | ph_rgh
        value        | Patch face values       | yes         |
    \endtable

    <patchName>
    {
        type            prghTotalHydrostaticPressure;
        value           uniform 0;
