- do not manually destroy the preconditioner. this is, and has always
been, owned by the ksp object and dies with its destruction.
the purpose of this is to get a more defined behaviour when doing the
gravity correction/upstream cell determination in the flux term.
I consider this to be just a kludge, so if anyone has a better idea of
what the composition for the non-existing gas and oil phases is,
please tell me. (note that generic compositional models do not exhibit
this issue because the composition of all fluids is always fully
defined because each component is assumed to dissolve in every phase.)
For these wells access its well_cells might read of the bounds
an array if they are the last wells in the struct. Therefore
we cannnot initialiue first_cell and the well control is uninitialized,
to.
With this commit theses wells are now detected and theor bhp, thp, and well_rates
are initialized to zero.
This reverts commit 09205dfa074af24b381595d02c15e799523ddb2b.
We cannot use the index as it might change for a well between different
report steps. Unfortunately the only persistent way to identify wells
over all report steps in the schedule seems to be the well name.
Before this commit we tried to compute whether a well is represented on
the processor using the grid information. Due to the overlap region and
possible completion on deactivated cells of the global grid this is not
even possible. E.g. we cannot distinguish whether a completion is just
not represented on the domain of a process or the corresponding cell is
not active in the simulation.
With this commit we refactor to passing the well manager an explicit
list of name of wells that should be completely neglected. This information
can easily by computed after the loadbalancer has computed partitions.
since
f(x) = 1 + 0.5*g(x)*g(x)
the derivative is
f'(x) = 0 + 2*0.5*g(x) * g'(x) = g(x)*g'(x)
note that the previous incorrect values do not affect the quality of
the obtained results (if the tolerance of the non-linear solver is
chosen to be small enough), but it may have deteriorated convergence
rates.
when well is closed due to rate economic limits, based on the auto
shut-in configuration, the well can be STOP or SHUT.
When well is closed due to all the connections are closed, it should be
SHUT.
In opm-material the wetting phase is the reference phase for two-phase
problems i.e water for oil-water system, but for flow it is always oil.
Add oil capillary pressure value to shift the reference phase to oil
