It seems like eclipse ignores NNCs with small transmissibility.
Small means less than 1e-6 for Eclipse (Even if it says that it
is ignoring values below 1e-5 and/or zero values)!.
This commit now implements the same threshold during IO.
Also fixes a bug when applying EDITNNC, it needs to have cell1<=cell2 to work.
Previously the vector of NNCData was passed in as a reference and sorted.
Unfortunately, it needed to be transformed later to meet all prerequisites.
With this commit we do this transformations in sortNncAndApplyEditnnc.
Furthermore EDITNNC data is passed by value as it is not needed
outside and should usually not be to big. It was copied outside anyway!
We first add all NNCs specified in the deck to the ouput
and then determine additional NNCs by iterating over all faces that
connect cells that are not connected in the underlying cartesian grid.
Therefore we need to make sure that we do not output NNCs twice
and for faults that also have a specified NNC we need to substract
the transmissibility specified via NNC.
- when an episode/report step is over, the next is started by endEpisode()
- the problem does not deal with updating the simulation time anymore
- rename `episodeIdx` in to `reportStepIdx` the 'EclWriter' because
this variable is -- and always has been -- the report step number
used by some parts of `opm-output`'s ECL writing code (the report
step number is equivalent to the episode index plus 1). IMO, the
output and parser code should be made more consistent in regard of
whether it expects 0-based or 1-based indices, but this is a story
for another day.
before patch, setting the `EnableEclOutput` parameter to `false`
resulted in the `eclWriter_` not to be allocated; yet it was used in
some places. this resulted in segfaults.
medium term, the output and restart file writing should be refactored:
the simulator does not need to be aware of this because it can be
accomplised in the problem's endTimeStep() method.
this avoids regressions for decks that use well testing and makes
`ebos` work as expected if UMFPACK is not available, but obviously it
will not work for decks that use multisegment wells in earnest.
`flow` is unaffected by this because it does not use this type tag.
Unfortunately, we first created NNC with applied EDITNNC and then
still used the original NNC data to set the transmissibility. Thus
we were actually ignoring EDITNNC.
This commit fixes this by using the data structure that has EDITNNC
applied.
maybe this needs to be reverted since the code in question can
cause the simulation to abort inadvertently.
As usual, `flow` is unaffected because this functionality is only
called in experimental mode and flow calls it itself.
this is part of the release maintainance. in this context "core
headers" means the ones which do not include the well model headers,
and only those which are concerned with non-exotic functionality,
e.g., the PolyhedralGrid and ALUGrid vanguards are not changed.
the only thing which this does so far is to introduce the respective
property and `ebos` will abort the run if the deck requests API tracking.
As usual for experimental features, `flow` is unaffected.
for some reason, this yields quite different results for norne than
the default variant, e.g. when comparing PRESSURE, we get
```
> compareECL -k PRESSURE -t UNRST ebos/NORNE_ATW2013 ebos_altidx/NORNE_ATW2013 1 1e-4
Comparing 'ebos/NORNE_ATW2013' to 'ebos_altidx/NORNE_ATW2013'.
Comparing PRESSURE...
Occurrence in first file = 9
Occurrence in second file = 9
Value index = 0
(first value, second value) = (254.195, 253.191)
Program threw an exception: [/home/and/src/opm-common/build-cmake/fake-src/examples/test_util/EclRegressionTest.cpp:161] Deviations exceed tolerances.
The absolute deviation is 1.00311, and the tolerance limit is 1.
The relative deviation is 0.00394624, and the tolerance limit is 0.0001.
```
IMO this is a bug, but the reasons for it are currently unknown.
these variants should cover most of the common use cases. That said,
there are no plans to provide simulators for combinations of blackoil
extensions or a "multiplexing" simulator like `flow`: If someone is
interested in e.g., an oil-water simulator with polymer and energy
enabled, a separate self-compiled executable should be added locally.
the idea is to compensate the residual of the final solution of a time
step by means of an opposing source term in the next time step.
This patch has been developed as a joint project with [at]totto82 and
[at]osae.
(`flow` is unaffected by this because for now drift compensation is an
experimental feature and thus disabled within the production
simulator.)
This enables `ebos` to run Norne and other non-trivial data
sets. While at it, adapt the tolerances by `ebos`.
This patch only affects the research simulator, i.e. `flow` is
unaffected by it.
