#include <dumux/porousmediumflow/2p/sequential/diffusion/mpfa/lmethod/3dpressurevelocityadaptive.hh>
Class for the calculation of 3d velocities from the pressure solution of an IMPES scheme using a grid adaptive MPFA L-method.
Can be used for calculating the complete velocity field before the solution of the transport equation (more efficient), or for face-wise velocity calculation directly in the transport solution (less efficient).
Remark1: only for 3-D Hexahedrons of quadrilaterals!
Remark2: Allowed difference in grid levels of two neighboring cells: 1

Volume correction term to correct for unphysical saturation overshoots/undershoots.
These can occur if the estimated time step for the explicit transport was too large. Correction by an artificial source term allows to correct this errors due to wrong time-stepping without losing mass conservation. The error term looks as follows:
\[ q_{error} = \begin{cases} S < 0 & \frac{S}{\Delta t} V \\ S > 1 & \frac{(S - 1)}{\Delta t} V \\ 0 \le S \le 1 & 0 \end{cases} \]
