This commit adds a new class that aggregates the *WEL vectors for
restart purposes. Using the data sources
- Simulation run's "Schedule" object
- Simulation run's "UnitSystem" object
- Current simulation step ("sim_step")
- WellRates object from simulator at the end of sim_step
- SummaryState object from Summary class at the end of sim_step
this class will fill in the (presently) known elements of the IWEL
(integers), SWEL (Real/float), XWEL (double precision), and ZWEL
arrays for output to a restart file. We distinguish contributions
of data sources extracted directly from the simulation deck from
those computed dynamically by the simulator--mostly to separate
concerns and to enable independent testing. If this introduces too
much computational overhead in actual simulation runs we can fuse
the member functions
AggregateWellData::captureDeclaredWellData()
AggregateWellData::captureDynamicWellData()
to reduce the number of loops over active wells.
The overall structure of this facility is that we have a single
templated function, wellLoop(), that calls user-defined "operations"
on each active well. Each of these operations in turn define a
subset of one of the {I,S,X,Z}WEL arrays pertaining to the
particular well. We furthermore put implementation functions into
namespaces according to the pertinent arrays.
Many thanks to my Equinor collaborators.
