This commit adds a simple facility for converting component rates at
surface conditions to voidage rates at reservoir conditions. It is
intentionally limited in scope and meant to be employed only in the
context of class FullyImplicitBlackoilSolver<> or something very
similar. In particular, class SurfaceToReservoirVoidage<> assumes
that it will be used to compute conversion coefficients for
component rates to voidage rates, and that those coefficients will
typically be entered into the coefficient matrix of a linearised
residual.
Add a trivial test just to demonstrate the setup and calling
process. This is not a feature or correctness test.
for the legacy C-style grid the unit test is more or less complete (it
does not test FAULTMULT and NNC, etc, but these could be added with
sufficient determination), for Dune::CpGrid it currently does not
really check anything because I have not found a good way for CpGrid
to produce the "global" intersection index of an intersection...
this is required to implement pore volume and permeability multipliers
as discussed with [at]bska and [at]joakim-hove.
Note that this implies that the DerivedGeology class can't be
instantiated anymore if there is no EclipseState object. Thus all code
paths and tests that don't load a deck are removed by this patch. If
this is undesireable, there are two options: First, don't require
EclipseState for DerivedGeology which would imply to make the about 10
required multiplier functions part of the
BlackoilPropertiesAdInterface, or second, one can copy-and-paste the
DerivedGeology class as it was before this patch, derive from a newly
introduced DerivedGeologyInterface and pass DerivedGeologyInterface
objects to the simulator. IMHO, the second solution would be a bit
better but it would involve substantial overhead to implement and to
maintain it.
Anyway, in the mean time simulators cannot be instantiated without
decks.
Manually resolved conficts in the following files
examples/sim_fibo_ad.cpp
opm/autodiff/FullyImplicitBlackoilSolver_impl.hpp
opm/autodiff/SimulatorFullyImplicitBlackoil_impl.hpp
In additions examples/sim_fibo_ad_cp.cpp was adapted to compile again.
This is intended to be used instead of the WellState class in the fully
implicit blackoil simulator. It contains a WellState to reuse the init()
method and to enable users to call functions requiring a WellState.
This is done with containment and an access member function,
basicWellState(), instead of with inheritance to minimize surprises.
This implements a superset of the interface as proposed in pull request
opm-core#496 for use with CpGrid.
It also adds some additional functionality needed in opm-autodiff.
This is done in preparation for adding a cpr-preconditioning solver
for the fully implicit black-oil system. The existing implementation
that concatenates the whole system and passes it to some linear solver
has been moved from a private function of FullyImplicitBlackoilSolver
to the class FullyImplicitSolverSimple.
To enable this decoupling, the residual struct has been copied out
of the FullyImplicitBlackoilSolver class and is now an independent
struct: FullyImplicitBlackoilResidual. The opportunity has been used
to replace the field mass_balance with material_balance_eq, which is
more precise.
This computes pressure differences with respect to the bottom-hole pressure
for each well perforation, based on the well flows. It is explicit and not
implicit, using the previous time step's flow rates to calculate the necessary
densities.
