The wells, FIP and initial output of NNCs is still handled
by code in opm-simulators. The plan is to move more of the
functionality to ebos.
All tests pass and MPI restart works
The wellModel is now persistent over the time steps,
with an update method called every reportStep/episode.
This allows the following simplifications:
1. move the wellState to the WellModel
2. add a ref to the ebosSimulator to the wellModel
3. clean up the parameters passed to the wellModel methods
4. move RESV handling to the WellModel and the rateConverter
5. move the econLimit update to the WellModel
to determine whether we will treat mutlisegment wells with
MultisegmentWell well model. Currently, it will be faulse by default.
It might be changed to be true by default when considering the
multisegment well model is well tested.
It can be something rather tricky. It looks like with simple trival
initization, it is difficutl to converge. But when there is change to
the well, direct copying will not work anymore. Will we also facing
convergence problem?
After the restructuring of of the well model, keeping an extra class for
the "Dense" model is not needed. The only thing still left in
WellStateFullyImplicitBlackoilDense was some solvent related stuff, this
PR moves this to WellStateFullyImplicitBlackoil and removes
WellStateFullyImplicitBlackoilDense.
In addition to a cleaning code this PR fixes missing solvent well output.
this is needed to avoid linker errors if this class ought to be used
in multiple compile units. IMO the main problem here is the use of an
_impl.hpp file.
Currently, the ReservoirState passed to the method and converted
to the initial solution of the Ebos simulator might have wrong
values in the ghost layer (this is the case for SPE9, Norne, Model 2).
This commit uses the syncOverlap method to update these values once they
are converted to the Ebos solution. The ReservoirState remains untouched.
This is enough to have consistent values throughout the simulation and only
introduces one additional communication step.
- pressure, rs and rv is averaged using hydrocarbon pore volume weights.
- pvtRegions is used as input in the conversion factor calculations.
- the pvt cell of the first well cell is used as the pvt index.
(Completing a well in two different PVT regions sounds like a very bad
idea anyway)
- FIP region support is added to the rate converter also for the ebos
interface.
1) Use the solution variable directly in RelativeChange(...)
2) Add a method in the RateConverter that takes the simulator instead of the state.
3) Pass the reservoir pressure directly to the well initialization.
4) Move convertInput(...) to SimulatorFullyImplicitBlackoilEbos.hpp.
This code is only used to convert the initial reservoir state.
5) Modify updateState(...). The solution variable is updated directly and adaptPrimaryVariable(...)
from ewoms is used to switch primary variables. An epsilon is passed to adaptPrimaryVarible(...) after a switch
of primary variables to make it harder to immediately switch back.
The following code used by flow_ebos still uses the reservoirState
1) the initialization
2) restart
3) output of the initial state
4) the step methods in AdaptiveTimeStepping and NonlinearSolver.
The reservoirState is not used by this methods, so after the initial step, an empty reservoirState is passed around in the code.
