Class
    Foam::saturationModels::function1Pressure
 
Description
    Saturation vapour pressure in terms of temperature in Kelvins. The
    saturation pressure in Pa is specified as a Foam::Function1 type, to enable
    use of, e.g. constant, polynomial, table values.
 
    Examples:
 
    \verbatim
        type function1;
        function
        {
            type                table;
            file                "filename.csv";
            format              csv;
            nHeaderLine         1;
            columns             (0 1);
            separator           ",";
            mergeSeparators     no;
            outOfBounds         clamp;
            interpolationScheme linear;
        }
    \endverbatim
