Class
    Foam::hTabulatedThermo
 
Description
    Enthalpy based thermodynamics package using non-uniform tabulated data for
    heat capacity vs temperature.
 
Usage
 
    \table
        Property     | Description
        Hf           | Heat of formation
        Sf           | Standard entropy
        Cp           | Specific heat at constant pressure vs temperature table
    \endtable
 
    Example of the specification of the thermodynamic properties:
    \verbatim
    thermodynamics
    {
        Hf              0;
        Sf              0;
        Cp
        (
            (200     1005)
            (350     1010)
            (400     1020)
        );
    }
