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
It has been replaced with the faster local-ad-based code, that is now
part of the integrated flow.cpp application.
We do not remove the old sequential implicit polymer simulators.
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.
The motivation for this PR is that currently the build fails on my
Ubuntu 17.10 laptop with two processes because that machine "only" has
8 GB of RAM (granted, the optimization options may have been a bit too
excessive). under the new scheme, each specialization of the simulator
is put into a separate compile unit which is part of
libopmsimulators. this has the advantages that the specialized
simulators and the main binary automatically stay consistent, the
compilation is faster (2m25s vs 4m16s on my machine) because all
compile units can be built in parallel and that compilation takes up
less RAM because there is no need to instantiate all specializations
in a single compile unit.
on the minus side, all specializations must now always be compiled,
the approach means slightly more work for the maintainers and the
flow_* startup code gets even more complicated.
No extra equation is added for polymer in the well equation.
Seperate executables are added for polymer: flow_ebos_polymer
and solvent: flow_ebos_solvent
Tested and verified on the test cases in polymer_test_suite
This PR should not effect the performance and results of the blackoil
simulator
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.
now we have BlackoilDetails.hpp which contains all stuff that is used
by flow_ebos as well as flow and which does not include anything from
Eigen, and we have BlackoilLegacyDetails.hpp which contains all stuff
that depends on Eigen (and is thus not required by flow_ebos)
some files (e.g., thresholdPressures.hpp) are already missing in the
master version of this file, but most of them were specific to the
`frankenstein` branch.

almost all of them were caused by recent changes in the master
branch:
- there were methods added which depend on the types `V` and
`DataBlock`. these do not make much sense in the context of the
frankenstein simulator. Also, these types are defined globally for the
whole Opm namespace in `BlackoilModelBase_impl.hpp` (which should be
prosecuted as a fellony IMO)! Besides this, their names are useless;
'V' is the letter which comes after `U` in the alphabet and when it
comes to computers basically everything can be seen as a chunk of data
(i.e., a `DataBlock`).
- it seems like the new and shiny dense-AD based well model was never
compiled with assertations enabled, at least some asserts referenced
non-existing variables.
- the recent output-related API changes were pretty unfortunate
because they had the effect of tying the (sub-optimal, IMO) internal
structure of the model even closer to the output code: as far as I can
see, `rq` does only make sense if the model works *exactly* like
BlackoilModelBase and friends. (for flow_ebos, this could be
replicated, but first it would be another unnecessary conversion step
and second, most of the quantities in `rq` are of type `ADB` and much
of the "frankenstein" excercise is devoted to getting rid of these.) I
thus reverted back to an old version of the output code and created a
`frankenstein` branch in my personal `opm-output` github fork.
it uses ebos for linearization of the mass balance equations and the
current flow code from opm-simulators for all the rest. currently, the
results match the ones from plain `flow` for SPE1, SPE9 and Norne, but
performance is not optimal: on SPE9, converting from and to the legacy
data structures takes about a third of the time to do the actual mass
balance assembly. nevertheless `flow_ebos` is almost as fast as plain
`flow` for SPE9. (for Norne `flow_ebos` is about 15% slower, even
though the results match quite closely. the reason for this is that it
requires more iterations for some reason.)
This commit adds sequential solvers, including a simulator variant
using them (flow_sequential.cpp) with an integration test (running
SPE1, same as for fully implicit).
The sequential code is capable of running several (but not all) test
cases without tuning or special parameters, but reducing ds_max a bit
(from default 0.2 to say 0.1) helps with transport solver
convergence. The Norne model runs fine (esp. with a little tuning). A
parameter iterate_to_fully_implicit (defaults to false) is available,
when set the simulator will iterate with alternating pressure and
transport solves towards the fully implicit solution. Although that
takes a lot extra time it serves as a correctness check.
Performance is not competitive with fully implicit at this point:
essentially both the pressure and transport models inherit the fully
implicit model and do a lot of double (or triple) work. The point has
been to establish a proof of concept and baseline for further
experiments, without disturbing the base model too much (or at all, if
possible).
Changes to existing code has been minimized by merging most such
changes as smaller PRs already, the only remaining such change is to
NewtonIterationBlackoilInterleaved. Admittedly, that code (to solve
the pressure system with AMG) is not ideal because it duplicates
similar code in CPRPreconditioner.hpp and is not parallel. I propose
to address this later by refactoring the "solve elliptic system" code
from CPRPreconditioner into a separate class that can be used also
from here
The Todd-Longstaff model is extended to incorporate pressure effects
The solvent viscosity is then caculated as
mu_eff = mu_s^(1-\alpha * \omega) * mu_mix^(\alpha * \omega)
where \omega accounts for the porous media effects and \alpha =
\alpha(pressure) accounts for the miscibility of the solvent and oil
when contacted.
The \alpha values can be given using the TLPMIXPA keyword
If no entries are given to TLPMIXPA the table specified using PMISC will
be used as default.
IF TLPMIXPA does not appear in the grid \alpha = 1 and the pressure
effect is neglected.
This is tested in test_solventprops_ad.cpp
