Class
    Foam::filmPyrolysisTemperatureCoupledFvPatchScalarField

Description
    This boundary condition is designed to be used in conjunction with surface
    film and pyrolysis modelling.  It provides a temperature 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 temperature is set using the film temperature
    - otherwise, it is set using pyrolysis temperature

    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            filmPyrolysisTemperatureCoupled;
        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   300; // initial temperature / [K]
    }
    \endverbatim
