Previously, we used the setStatus method to set wells that do not
exist on the local grid to SHUT. Or at least this is what I thought
that ```well.setStatus(timestep, SHUT)```. Unfortunately, my
assumption was wrong. This was revealed while testing a parallel run
with SPE9 that threw an expeption about "Elements must be added in
weakly increasing order" in Opm::DynamicState::add(int, T). Seems like
the method name is a bit misleading.
As it turns out the WellManager has its own complete list of active
wells (shut wells are simply left out). Therefore we can use this
behaviour to our advantage: With this commit we not only exclude shut
wells from the list, but also the ones that do not exist on the local
grid. We even get rid of an ugly const_cast.
Currently, I have running a parallel SPE9 test that has not yet
aborted.
In a parallel run each process only knows a part of the grid. Nevertheless
it does hold the complete well information. To resolve this the WellsManager
must be able to handle this case.
With this commit its constructor gets a flag indicating whether this is
a parallel run. If it is, then it does not throw if a well has cells that
are not present on the local part of the grid. Nevertheless it will check
that either all or none of the cells of a well are stored in the local part
of the grid.
Wells with no perforated cells on the local will still be present but set to SHUT.
With this commit the WellsManager will check the status of completions
before adding them to the internal struct wells
datastructure. Completions can be in the four states:
OPEN, SHUT, AUTO, POPN
Completions with state == SHUT will be ignored, wheras the wellsmanager
will throw if the states AUTO or POPN are encountered. The WELOPEN
keyword can also have the value 'STOP'; for completions that is
translated to 'SHUT' by Schedule object.
Shut wells are not added to the well list and thus not considered in the
simulator.
The shut well test in test_wellsmanager is modified to assert this
behaviour.
BUG: This change provokes an assert in the EclipeWriter as number of
wells in wellstate is different from number of wells in the schedule.
This commit extends the feature set of the WellsManager to support
horizontal ("X" and "Y") completions and include the net-to-gross
ratio in the Peaceman index ("Completion Transmissibility Factor,
CTF") of a well completion. The NTG factor is included if present
in the input deck represented by the "eclipseState".
There are two separate, though related, parts to this commit. The
first part splits the calculation of Peaceman's "effective radius"
out to a separate utility function, effectiveRadius(), and
generalises WellsManagerDetail::computeWellIndex() to account for
arbitrary directions and NTG factors. The second part uses
GridPropertyAccess::Compressed<> to extract the NTG vector from the
input if present while providing a fall-back value of 1.0 if no such
vector is available.
Note: We may wish to make the extraction policy configurable at some
point in the future.
This commit tightens the function header of method
WellsManager::createWellsFromSpecs()
to accept a reference-to-const 'cartesian_to_compressed' map. It
used to be a complete, copy-constructed object, so this is a slight
performance enhancement as we no longer need to copy a (somewhat)
large object on every call to the method.
This commit generalises the implementation of utility function
'getCubeDim' to support arbitrary number of space dimensions. In
actual practice there's no change in features as we only really use
a compile-time constant (= 3) to specify the number of space
dimensions.
Removed conflicts in
opm/core/wells/WellsManager.cpp
that were due to the change
```diff
- pd.well_index = WellsManagerDetail::computeWellIndex(radius, cubical, cell_perm, completion->getDiameter());
+ pd.well_index = WellsManagerDetail::computeWellIndex(radius, cubical, cell_perm, completion->getSkinFactor());
```
in WellsManager::createWellsFromSpecs which moved from WellsManager.cpp to WellsManager_impl.hpp file in a previous commit.
