Class
    Foam::fv::boundedConvectionScheme
 
Description
    Bounded form of the selected convection scheme.
 
    Boundedness is achieved by subtracting div(phi)*vf or Sp(div(phi), vf)
    which is non-conservative if div(phi) != 0 but conservative otherwise.
 
    Can be used for convection of bounded scalar properties in steady-state
    solvers to improve stability if insufficient convergence of the pressure
    equation causes temporary divergence of the flux field.
