Class
    Foam::icoPolynomial
 
Description
    Incompressible, polynomial form of equation of state, using a polynomial
    function for density.
 
    Coefficient mixing is very inaccurate and not supported, so this equation of
    state is not applicable to mixtures.
 
    The polynomial expression is evaluated from:
 
    \verbatim
            rho = 1000 - 0.05*T + 0.003*sqr(T)
    \endverbatim
 
Usage
    \table
        Property     | Description
        rhoCoeffs<8> | Density polynomial coefficients
    \endtable
 
    Example specification of the icoPolynomial equation of state:
    \verbatim
    equationOfState
    {
        rhoCoeffs<8>    ( 1000 -0.05 0.003 0 0 0 0 0 );
    }
    \endverbatim
