Detailed Description

CompositionalMultiphaseReservoirFVM strategy.

Labels description stored in point_marker_array 0 = reservoir pressure 1 = reservoir density ... = ... (reservoir densities) numResLabels - 1 = reservoir density numResLabels = well pressure numResLabels + 1 = well density ... = ... (well densities) numResLabels + numWellLabels - 2 = well density numResLabels + numWellLabels - 1 = well rate

3-level MGR reduction strategy which seems to work well for 2 components:

• 1st level: eliminate the reservoir density associated with the volume constraint
• 2nd level: eliminate the rest of the reservoir densities
• 3rd level: eliminate the pressure
• The coarse grid is the well block and solved with ILU(0)

Todo:

:

• Use block Jacobi for F-relaxation/interpolation of the reservoir densities (2nd level)
