Class
    Foam::surfaceTensionModel
 
Description
    Abstract base-class for surface tension models which return the surface
    tension coefficient field.
 
Usage
    Example of the surface tension specification:
    \verbatim
        sigma
        {
            type                <surface tension model type>;
            <coefficient name>  <coefficient value>;
            .
            .
            .
        }
    \endverbatim
    For simplicity and backward-compatibility the constant value format is
    also supported, e.g.
    \verbatim
        sigma           0.07;
    \endverbatim
