with multi-segments, the segment pressure can be lower than the bhp, so
it is not desirable to use spres_lower_limit to limit the segment
pressure. We only use spres_lower_limit to limit the bhp, which is still
valid until we begin using bhp limit lower than 1 bar.
Previously, if the problem occured on an MPI process with rank other
than zero the the logging would not seen (at least in the output
files). Now together with the previous commit the problem should be
logged together with the well name and calling method.
The well dfactor is scaled by the well index
If postive the connection dfactor is threated as a well factor
and also scaled. If negative the connection dfactor is not scaled
This should replace OPM_DEFLOG_THROW in places where the problem
category is more appropriate than the error category.
In this commit, uses of OPM_DEFLOG_THROW have been replaced whenever
the exception class used was NumericalProblem.
when we do the local solve for well equations, control/status will be
updated during the iteration process, such that the converged well gets
correct control/status regarding to the current reservoir state.
various change in the other parts of the code were made to make the
function work as intended.
This commit activates the support for calculating WBPn summary
result values per well in parallel. To affect the calculation we
add two new data members in BlackoilWellModelGeneric:
- conn_idx_map_:
Maps well's connection index (0..getConnections().size() - 1) to
connections on current rank. Its local() connections are
negative 1 (-1) if the connection is not on current rank, and a
non-negative value otherwise. The global() function maps well
connections on current rank to global connection ID for each
well. Effectively the reverse of local(). Finally, the open()
function maps well connections on current rank to open/flowing
connections on current rank. Negative 1 if connection is not
flowing.
- wbpCalculationService:
Parallel collection of WBPn calculation objects that knows how
to exchange source and result information between all ranks in a
communicator. Also handles distributed wells.
We furthermore need a way to compute connection-level fluid mixture
density values. For the standard well class we add a way to access
the StandardWellConnection's 'perf_densities_' values. However,
since these are defined for open/flowing connections only, this
means we're not able to fully meet the requirements of the
WELL/ALL
WPAVE depth correction procedure for standard wells. The
multi-segmented well type, on the other hand, uses the fluid mixture
density in the associated well segment and is therefore well defined
for ALL connections. OPEN well connections are supported for both
well types.
This commit adds logic and backing storage in the SegmentState to
provide the segment level summary vectors
- SDENx -- Phase density of phase 'x' (O, G, W)
- SDENM -- Mixture density without flowing fraction exponents
- SMDEN -- Mixture density with flowing fraction exponents
We defer the calculation of SDENM and, especially, SMDEN, to the
MultisegmentWellSegments class since this class maintains the
current flowing fractions.
