This only makes these transmissibilities available for parallel
computations. The reason is that in the sequential case, they do not
need to be computed during grid creation and they are are also
accessible via the problem object.
Face centers are computed using the cell corners. With this
implementation the face center seen from a cell may be different from the
face center seen from its neighbour.
Face normals with area lenghts are calculated using the face corners
directly not using a triangulation point in the center of the face.
This gives transmissibility almost equal to eclipse.
hopefully this makes standalone `ebos` arrive at the same initial
condition as `flow_ebos` if both, SWATINIT and threshold pressures are
enabled. we need to calculate the initial condition twice either
threshold pressures and SWATINIT are enabled. (`ebos` and `flow_ebos`
diverged after OPM/opm-core#1129.)
the proposed patch is a kludge IMO, but in the light that in my
opinion, SWATINIT and threshold pressures are both physically not
justified and given the fact that SWATINIT must not be considered for
the threshold pressues should be considered to be a bug of the
reference simulator, I think the patch is okay.
Judging from ParallelDebugOutput.hh this is what is should be.
Before this commit it was empty as it had space reserved but never
any entries pushed (they were inserted with operator[]).
This reverts commit dde79daf4ec2004148a58250c4c8af5390251689.
Judging from ParallelDebugOutput.hh this should not be a map from element
index to interior element index, but an a list of indices of all interior
elements. Therefore we need to reserve and later on push_back.
This reverts commit 09db2fd412abe4b8a2f52274bcc0041e4b20a94d.

Previously distributedCartesianIndex was resized and afterwards all
entries were added with push_back. Therefore the array was twice as
big as expected and contained wrong values in the front.
With this commit we insert the values using random access. Thus the
size is as expeceted and the index of the entries do not depend on the
order of the grid traversal.
While it may not produce memory errors it is semantically wrong to insert
entries with random acces into a vector that has reserved enough memory to
hold the values but still has size 0.
Due to the nature of CpGrid (manages one shared pointer to the equil grid
and one the distributed grid) this should be faster as it only adjusts one
shared pointer.
we now store the maximum oil-water capillary pressure and apply it to
the material parameters later. this simplifies things within the
EquilInitializer somewhat and also allows external code (i.e.,
flow_ebos) to choose when SWATINIT gets applied.
this makes creating the grid a bit slower because the
transmissibilities need to be calculated twice: once for the
sequential grid and once for the distributed one. while corresponds to
the way `flow_legacy` does the load balancing and it should allow
better results, this does not seem to be the case for the Norne deck
if ZOLTAN is not available:
After loadbalancing process 3 has 4413 cells.
After loadbalancing process 2 has 12390 cells.
After loadbalancing process 0 has 13629 cells.
After loadbalancing process 1 has 21253 cells.
i.e., process 1 is responsible for almost 5 as many cells as process
3.
before, they were undefined for phases which exhibited zero mobility
in both directions. since in this case the flux is zero (and thus the
upstream direction does not matter), the correctness is unaffected by
this patch. (still, I consider it to bug and valgrind also complained
about it.)
