in particular, the rock compressibility effects are not considered in
the FIP numbers anymore. While I'm not sure if this is correct or not,
it at least makes the results consistent with those produced by
'flow_legacy'.
All simulators now use SimulationDataContainer to store intermediate data that
is passed to the output Solution container. This is in cases not the most
efficient way, but it's unified to avoid errors from code duplication.
The initial solution in ebos and in flowebos are different in cases where
swatinit is present. Pass the initial solution and recalculate the
intensive quantities make sure that the flowEbos initial solution is
used.
the most significant change is that only a "PhaseUsage" object must be
passed to its constructor instead of a full "fluid object". also, the
pointers to the vector of "active" phases has been converted into a
full object. (this helps to avoid potential use-after-free errors.)
* https://github.com/OPM/opm-simulators:
[bugfix] add defunct_well_names to BlackoilModelEbos.
[bugfix] fix ownerMask for parallel FIP code.
flow_ebos: tell the ebos in ourselves to not handle SWATINIT
[bugfix] Make initialization work in parallel for flow_ebos.
[bugfix] make flow_ebos work when no wells are present.
flow_ebos: only instantiate the grid once
this patch also includes code to make FlowMainEbos more autonomous
(i.e. it does not derive from FlowMainBase anymore). this allows more
flexibility how and what stuff gets created.
this changes the conversion of the results to hopefully make it work
with twophase simulations. Note that flow_ebos still does not work
because there is a crash in the well model that I don't understand
(and also, I've disabled an assertation in the well model plus I'm not
completely sure if the conversion code need to do something about the
primary variables in the twophase case).
mainly, the "linsolver_" attribute is called "istlSolver_" in the
BlackoilModelEbos class. Also, this problem possibly only occured if
MPI was enabled...
- restrict pressure changes. Set default to 1.0 (this also effects flow)
- change default number of linear iterations to 150
- tell stabilized newton the residual occilates even if it occilates in
only one phase (this also effects flow)
- avoid problems realated to division on small numbers
Tested on SPE9, norne and Model 2 with significant improvments.
