Description
    This boundary condition calculates a (liquid) compressible density as a
    function of pressure and fluid properties:
 
        \f[
            \rho = \rho_{l,sat} + \psi_l*(p - p_{sat})
        \f]
 
    where
 
    \vartable
        \rho    | density [kg/m3]
        \rho_{l,sat} | saturation liquid density [kg/m3]
        \psi_l  | liquid compressibility
        p       | pressure [Pa]
        p_{sat} | saturation pressure [Pa]
    \endvartable
 
    The variables \c rholSat, \c pSat and \c psil are retrieved from the
    \c thermodynamicProperties dictionary.

    Example of the boundary condition specification:
    \verbatim
    myPatch
    {
        type        fixedPressureCompressibleDensity;
        p           p;
        value       uniform 1;
    }
    \endverbatim
