 \rho h_s = \rho c_p T = \rho T \sum_\alpha Y_\alpha c_{p,\alpha} = \rho R T \left(\frac{\gamma}{\gamma-1}\right)\sum_\alpha \frac{Y_\alpha}{W_\alpha} = \rho \frac{R T}{\overline{W}} \left(\frac{\gamma}{\gamma-1}\right) = \bar{p}\left(\frac{\gamma}{\gamma-1}\right)
 \end{align}
-Therefore, if $\bar{p}$ is constant and uniform then $\rho h_s$ is constant and uniform.  Consequently, $\partial (\rho h_s)/\partial t = 0$ and $\nabla (\rho h_s) = 0$, so we require no corrections to the divergence expression.  This improves the speed of the code since these divergence corrections are rather expensive.  To employ this simplification, the user enters \emph{both} {\ct CONSTANT\_SPECIFIC\_HEAT\_RATIO=.TRUE.} and {\ct STRATIFICATION=.FALSE.} on the {\ct MISC} line of the input file.
