Class
    Foam::dynamicPressureFvPatchScalarField
 
Description
    This boundary condition provides a dynamic pressure condition. It subtracts
    a kinetic energy term from a reference pressure to get a value which is
    fixed on the boundary. It forms the base class for the total and
    entrainment pressure conditions.
