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.
These can be used to manage state in the well models, and will
be used in the NLDD solver option. Also added the setupDomains()
method, as the getters and setters are working on a domain basis.

We guarantee the objective through enforce zero values for the WQTotal
primary variable during the initialization and update process during the
Newton solution.
hopefully, it begins at a reasonably good initial point. When the Newton
iteration begins with certian solution region, the nonlinear solution
might fail.
