Class
    Foam::filmPyrolysisVelocityCoupledFvPatchVectorField
 
Description
    This boundary condition is designed to be used in conjunction with surface
    film and pyrolysis modelling.  It provides a velocity boundary condition
    for patches on the primary region based on whether the patch is seen to
    be 'wet', retrieved from the film alpha field.
 
    \li if the patch is wet, the velocity is set using the film velocity
    \li otherwise, it is set using pyrolysis out-gassing velocity
 
    Example of the boundary condition specification:
    \verbatim
        myPatch
        {
            type            filmPyrolysisVelocityCoupled;
            phi             phi;      // name of flux field (default = phi)
            rho             rho;      // name of density field (default = rho)
            deltaWet        1e-4;     // threshold height for 'wet' film
            value           uniform   (0 0 0); // initial velocity / [m/s]
        }
    \endverbatim
