This commit introduces a new top-level "manager" for all saturation
function consistency checks. This component associates collections
of saturation function curves with per-cell or per-region end-point
definitions and provides an interface to run all checks for all
interior entities (i.e., active cells) in a DUNE grid view. We form
one set of SatfuncConsistencyChecks objects for each
SatfuncCheckPointInterface<> object, thereby enabling running the
same set of consistency checks for both the unscaled, tabulated,
per-region saturation functions and the per-cell scaled saturation
functions. The latter is executed only if the run enables end-point
scaling for the saturation functions while the former is executed
only if the run does not enable end-point scaling.
At present we're limited to reversible and non-directional
saturation functions for the drainage process only, but those
restrictions will be lifted in due time.
As an aid to enabling the pertinent individual checks, we add a
private factory function which considers the run's active phases and
whether or not the run uses the alternative, three-point horizontal
scaling method ("SCALECRS = YES").
This commit introduces a set of callback functions, packaged in an
abstract base class SatfuncCheckPointInterface<Scalar>, for querying
and populating the saturation function end-points that get probed by
the individual consistency checks. Member function
SatfuncCheckPointInterface::pointID(cellIdx)
translates the active cell index 'cellIdx' into a point ID, assumed
to be unique on at least the current MPI rank. This function will
return 'nullopt' if the 'cellIdx' is not eligible for this
particular end-point. This typically happens for the region based
tabulated (unscaled) saturation function checks when the 'cellIdx'
happens to be in a region that's already been visited. Member
function
SatfuncCheckPointInterface::populateCheckPoint(cellIdx, endPoints)
fills in (assigns) all data members of the 'endPoints' structure
with the pertinent values for the active cell 'cellIdx'.
We implement this interface for the tabulated/unscaled end-points in
derived class UnscaledSatfuncCheckPoint<Scalar> and for the scaled
end-points in derived class ScaledSatfuncCheckPoint<Scalar>. The
former keeps track of which saturation regions have been visited
and short-circuits its 'pointID()' member function based on that
information while the latter uses an instance of the former in order
initialise the 'endPoints' structure in its populateCheckPoint()
member function.
This commit introduces consistency checks for the scaled displacing
saturation in the three point horizontal scaling method
(SCALECRS=YES). These plug into the framework introduced in commit
c3939c544 (PR #5438). We implement the following two checks
- SGCR < 1-SOGCR-SWL < SGU
- SWCR < 1-SOWCR-SGL < SWU
which collectively guarantee a mobile displacing oil saturation in
the two phase gas/oil and oil/water systems.
