Commit 6295bd08c (PR #6238) restricted RFT data reporting to only
those wells that are owned by the current rank. In so doing,
however, we failed to properly account for distributed wells. Such
wells will typically have RFT contributions from multiple MPI ranks
in a parallel run and we did not allow for this situation.
Moreover, as the simulator by default will distribute "inactive"
wells--wells that are never opened, but which exist primarily to
collect RFT-style data--the problem becomes more pronounced for
these wells.
We solve the problem by splitting the RFTContainer's "wellQuery_"
into two responsibilities. One for determining if a particular
named well is owned by the current rank and another for determining
if the well is intersected on the current rank. The latter will be
true for all ranks that have local well connections for the named
well. This, in turn, means that the constructor now takes two
predicate functions instead of the one we originally used.
Furthermore, member function RFTContainer::allocate() will create
internal data structures for all potential connections on all ranks
that share a well, but RFTContainer::addToWells() will still collect
the RFT data only on the rank that owns the well.
Finally, we implement the owning vs. intersecting distinction for
the black-oil output module through a new member function
bool BlackoilWellModelGeneric<>::hasLocalCells(name) const
while the compositional output module retains the original
owning-is-intersecting behaviour. We do not support distributed
wells in compositional runs at the time of writing.
