vp- coupled linear system: upper bound for ratio between velocity and pressure entries, VELOCITY EQUATION
For example,
In the coupled linear system "vp-", for the velocity equation(s), the ratio of the matrix entries referring to velocity and pressure
can be limited, such that the off-diagonal submatrix does not become too dominant. I.e.
\begin{align} \frac{Iv}{Ip}>\epsilon_V\end{align}
'Iv' is the order of magnitude of the velocity relevant parts
'Ip' is the order of magnitude of the pressure relevant parts
in the VELOCUTY equation.
