using the eWoms API for wells, the Schur compliment was not applied at
all. If `BlackOilWellModel::linearize()` was made non-trivial, the
Schur complement was applied twice in `flow`. With this patch, we only
apply this using the eWoms API (in
`BlackOilWellModel::linearize()`). I could not observe a signficant
effect on the convergence behaviour of `flow` for the cases which I
tested (Norne and realization 5 of Model 2).
I tested #1712 without deriving the `EclFlowProblem` type tag from
`FlowIstlSolver`, and it worked because the linear solver was still
`Opm::ISTLSolverEbos` because the linear solver is set via the
`LinearSolverSplice` a few lines down.
This time, I verified that the
`Ewoms::Linear::ParallelBiCGStabSolverBackend` was used if the
offending line was commented out. also, Norne worked fine with the
default solver as long as the Schur complement for the wells was done
explicitly.
Finally, the naming of the eWoms API is a bit inconsistent
(`setMatrix()` vs. `setResidual()`). any opinions here? I'm fine with
whatever.

correctly. Also slight refactoring of how component names for output
are handled.
Note: the communication and reduction for computing reservoir
convergence is not done by gathering ConvergenceReports, but
as before, using the convergenceReduction() method.
* fixed the issue of including ghost cells in preconditioning, by zeroing out ghost rows and setting the diagonal to a large value.
* move altering of matrix to a function
* blockwise modification of matrix
* add findOverlapRowsAndColumns in BlacoilDetail. Add call to findOverlapRowsAndColumns in constructor of BlacoilModelEbos. Change makeOverlapRowsInvalid, by looping over precalculated inddies instead of grid
* Better formatting
also, clean them up a bit:
- do not use the intensive quantities cache directly anymore. (i.e.,
that code should now work if the IQ cache is disabled)
- do not fiddle with the global Jacobian matrix and residual vector
directly. Instead, implement the water fluxes to the reservoir as a
source term like wells.
one thing that did not become fully clear to me is if each aquifer
ought to be assumed to be in contact with the whole reservoir or just
a few cells on the boundary. The current implementation goes down the
former path, while, without any deeper knowledge, I would rather
suppose that the latter applies. maybe my understanding of this is
just too limited, though.
this has several advanges:
- a consistent and complete help message is now printed by passing the
-h or --help command line parameters. most notably this allows to
generically implement tab completion of parameters for bash
- the full list of runtime parameters can now be printed before the simulator
has been run.
- all runtime parameters understood by ebos can be specified
- no hacks to marry the two parameter systems anymore
- command parameters now follow the standard unix convention, i.e.,
`--param-name=value` instead of `param_name=value`
on the negative side, some parameters have been renamed and the syntax
has changed so calls to `flow` that specify parameters must adapted.
these objects are only used by flow_legacy, so not having to deal with
them anymore lets non-legacy flow avoid to jump through a lot of hoops
for the sake of having a common API.
this required a fork of the NonlinearSolver and AdaptiveTimeStepping
classes. this is not a problem because the original classes would get
pruned to look like the new ones once flow_legacy gets moved out of
the opm-simulators module.
The energy conservation is enabled by specifying either TEMP or
THERMAL in the deck. The deck also needs to contatin relevant fluid and rock
heat properties.
The blackoil + energy equations are solved fully implicit.
an empty string is interpreted as "write the output files into the
same directory as the input". this is the current 'flow' default
behavior, plain ebos uses "." as the default location for output,
i.e., the current directory from which the simulator is run from.
Use a relaxed tolerance for individual cells (CNV) when iter >
max_strict_iter.
tolerance_cnv_relaxed_ is defauled to 1.0e9
This assure the same behaviour as current master, where CNV criterion is
ignored when iter > max_strict_iter
TODO: Test this with a stricter default ( <= 1.0)
