Description🔗

The nutkFilmWallFunction is boundary condition that provides a turbulent viscosity condition when using wall functions, based on turbulence kinetic energy, for use with surface film models.

Usage🔗

The condition requires entries in both the boundary and field files.

Boundary file🔗

<patchName>
{
    type            patch;
    ...
}

Field file🔗

<patchName>
{
    // Mandatory entries
    type            nutkFilmWallFunction;

    // Optional entries
    filmRegion      <word>;
    B               <scalar>;
    yPlusCrit       <scalar>;

    // Inherited entries
    ...
}
