This is a relic of the way we originally handled gravity. The member
remained after the change, and is now a major time-consumption sink
due to the unfortunate fact that it is computed every time step
(unnecessary), and because the gravityOperator() function (now removed)
was very unperformant after changing to use the faceCells() function.
this means that the NTG, MULTPV and MULT[XYZ]-? keywords are now
supported.
Actually FAULTS and MULTFAULT are supported too, but that's abstracted
away by opm-parser's TransMult class. (Kudos to [at]joakim-hove for
implementing this.)
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.
Commit 5112b8a misinterpreted the role of index 'i' and, as a result,
installed code that would only define one-sided gravity potentials of
the first cell (roughly)--albeit eventually using the geometry of the
last active cell.
This commit restores the original, intended behaviour.
Class FullyImplicitBlackoilSolver<Grid> already features a list of
"all" cells, built at object construction time. There's no need to
re-compute that list on every call to variableState() (when Gas is
active).
The "xvar" exists only if Gas is active. Therefore, we cannot
extract that variable from "vars" unless we know that Gas is an
active phase. Failing to do so would wrongfully increment 'nextvar'
whence the final BHP variable would be an out-of-bounds access.
Methods 'computeRelperm()' and 'computePressures()' *always* return
a three-element vector of phase properties. We must therefore
translate to canonical phase indices before indexing into the
results.
i.e. reading the grid properties from EclipseState instead of from the
raw deck. This requires that all deck files exhibit a GRID and a
SCHEDULE section or else EclipseState will throw in the constructor.
Removing the bool input parameters osicllate and stagnate from the
stablizeNewton(). Basically, the value omega will decide if the
relaxation will be applied.
