Class
    Foam::noFlux
 
Description
    Zero mass flux boundary condition to specify pressure gradient. The special case of HydrothermalMassFluxPressure with q=0
 
    Example of the boundary condition specification:
    \verbatim
    myPatch
    {
        type            noFlux;
    }
    \endverbatim
