This is done since the solver will need to be able to switch well controls
during Newton iterations. The current control specified in the Wells struct
will be used as default and initial value for currentControls().
Conflicts:
opm/autodiff/FullyImplicitBlackoilSolver.cpp
To resolve conflicts, WellState was changed to WellStateFullyImplicitBlackoil
in multiple places, and perfRate() changed to perfPhaseRate() in
WellDensitySegmented.
This is intended to be used instead of the WellState class in the fully
implicit blackoil simulator. It contains a WellState to reuse the init()
method and to enable users to call functions requiring a WellState.
This is done with containment and an access member function,
basicWellState(), instead of with inheritance to minimize surprises.
Todo: incorporate WellDensitySegment. Currently values of the pressure
drop is hardcoded to make the rest of the code work
Todo: make it possible to shut perforation with crossflow.
if done the other way round we would make an assertation in TimeMap
false and also the values returned by SimulationTimer would be for the
next time step and not the current one...
The code was partially kept as a reminder to implement
proper well reporting and mass balance reporting. Now
well reporting has been taken care of, so we remove
the code.
This computes pressure differences with respect to the bottom-hole pressure
for each well perforation, based on the well flows. It is explicit and not
implicit, using the previous time step's flow rates to calculate the necessary
densities.
The simulator now handles live gas as well as live oil.
The primary variables are Po,Sw and Rs,Rv or Sg depending on fluid
condition
State 1 Gas only (Undersaturated gas): Po, Sw and Rv
State 2 Gas and oil: Po, Sw and Sg
State 3 Oil only (Undersaturated oil): Po, Sw and Rs
This commit includes:
1. New interfaces for the vapor oil/gas ratios (Rv)
2. Modifications in the equations to handle rvs
3. New definition of ADI variable to handle changing primary variables
4. Modifications in the solution updates to handle changing primary
variable
5. Some changes in the appleyard process to sync with Mrsts livegas
implementation.
NOTE:
The implementation is tested on the liveoil cases SPE1 and a simplified
SPE9 and produces the same results as the old code.
The simulator is not yet able to converge on SPE3 with livegas present.
For SPE3 to converge a more robust well implementation is needed. The
current simulator reproduce the results of Mrst when a similar well
model is used in Mrst as is currently implemented OPM.
The pvt interface is extened to handle wet gas
1. A function for rvSat is added to the interface
2. An interface that takes rv and the fluid condition as an input for
the gas properties is added. The old interface without rv and the fluid
condition is kept in the file.
3. The new interface is implemented in BlackoilPropsAd and
BlackoilPropsAdFromDeck.
A simulator that tests wet gas is not yet implemented.
