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.
      - if the patch is wet, the velocity is set using the film velocity
      - otherwise, it is set using pyrolysis out-gassing velocity
 
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        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
