Class
    Foam::regionFaModels::liquidFilmModel
 
Description
    Thin film model.
 
Usage
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        // Mandatory entries
        thermo                  <dict>;
 
        // Optional entries
        T0                      <scalar>;
 
        // Inherited entries
        ...
    }
    \endverbatim
 
    where the entries mean:
    \table
      Property   | Description                      | Type  | Reqd   | Deflt
      thermo     | Liquid thermodynamics properties | dict  | yes    | -
      T0         | Reference temperature [K]       | scalar | choice | -
    \endtable
