    type                velocityFilmShell;

    active              true;
    infoOutput          true;

    pRef                1e5;
    T0                  300;

    deltaWet            1e-4;
    h0                  1e-8;

    zeroWallVelocity    true;

    thermo
    {

    }

    turbulence          laminar;

    laminarCoeffs
