vp- coupled linear system: lower bound for ratio between pressure and velocity entries, PRESSURE EQUATION

For example, In the coupled linear system "vp-", for the pressure equation, the ratio of the matrix entries referring to pressure and velocity can be limited, such that the off-diagonal submatrix does not become too dominant. I.e. \begin{align} \frac{IIp}{IIv}>\epsilon_P\end{align} 'IIp' is the order of magnitude of the pressure relevant parts 'IIv' is the order of magnitude of the velocity relevant parts in the PRESSURE equation.
