Detailed Description

This boundary condition provides a coupled velocity condition between a primary region (3D mesh) and a liquid-film model (2D mesh).

Usage

Example of the boundary condition specification:

<patchName>
{
    // Mandatory entries
    type                velocityFilmShell;
    liquidFilmModel     <word>;

    // Optional entries
    zeroWallVelocity    <bool>;

    // Inherited entries
    ...
    active              <bool>;
    infoOutput          <bool>;
    U                   <word>;
    pRef                <scalar>;
    T0                  <scalar>;
    deltaWet            <scalar>;
    h0                  <scalar>;

    thermo
    {
        H2O;
    }

    turbulence          laminar;
    laminarCoeffs
    {
        friction        ManningStrickler;   // Wall friction model
        n               0.005;              // Manning number
        Cf              0.9;                // Gas friction
    }

    injectionModels
    (
        curvatureSeparation
    );

    forces ();

    curvatureSeparationCoeffs
    {
        definedPatchRadii  0;
    }

    region              film;
    value               uniform (0 0 0);
}
