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.
