the idea is to compensate the residual of the final solution of a time
step by means of an opposing source term in the next time step.
This patch has been developed as a joint project with [at]totto82 and
[at]osae.
(`flow` is unaffected by this because for now drift compensation is an
experimental feature and thus disabled within the production
simulator.)
for some reason, libraries produced for a module are not linked to the
executables of the module by the default build system. so far this did
not matter for `ebos` but with this PR, it starts using stuff from
`libopmsimulators`...
This enables `ebos` to run Norne and other non-trivial data
sets. While at it, adapt the tolerances by `ebos`.
This patch only affects the research simulator, i.e. `flow` is
unaffected by it.
these parameters where introduced with support for the TUNIING keyword
in `ebos`. since `flow` implements its own time stepping these
parameters are unused and should thus be hidden from view in it.
the former is caught by `ebos`, while the latter isn't. Alternatively,
this can be fixed by deriving `LinearSolverProblem` from
`NumericalIssue`, if preferred.
this bitrot a bit because it was never seen by the compiler. (I still
did not check if `ebos` compiles and works if `CpGrid` is replaced by
dune-alugrid or `PolyhedralGrid`.)
the convergence behaviour can now be understood and the report step
information is printed, too. This does not affect `flow`, becase it
implements its own newton and time stepping routines.
the speedup gained by parallelism here are simply not worth the
headaches.
note that `flow` is unaffected by this because it uses
`Opm::BlackoilWellModel`.
the original purpose of those is to provide a checkpoint/restart
mechanism using an ad-hoc file format. They might also be useful for
implementing the adjoint functionality, though.
using the eWoms API for wells, the Schur compliment was not applied at
all. If `BlackOilWellModel::linearize()` was made non-trivial, the
Schur complement was applied twice in `flow`. With this patch, we only
apply this using the eWoms API (in
`BlackOilWellModel::linearize()`). I could not observe a signficant
effect on the convergence behaviour of `flow` for the cases which I
tested (Norne and realization 5 of Model 2).
Usage
BCRATE
1 1 1 1 1 10 X WATER 1e-7 /
This will inject 1e-7 of water (mass/time/length/length) on the x side of the
boundary cells with cartesian index [1 1 1] to [1 1 10]
this is a compile time switch with the intention to be able to more
easily turn experimental features that are not yet considered to be
production quality on and off. DUNE has a similar mechanism (i.e., the
`DUNE_GRID_EXPERIMENTAL_GRID_EXTENSIONS` macro), but it relies on
the preprocessor.
For now, the property does not have any effect.
this hopefully makes the purpose of `ebos` clear in its
description. this prose should be interpreted as "if you use ebos in
production, you are on your own and you should only expect a very
limited amount of support (or even sympathy) if something breaks".
in particular the missing synchronization after restarts was very
nasty to find. thanks a ton for pointing this out!
also, IIRC changing DR[SV]DT in the schedule section has been working
properly for a while, so the comment which stated the opposite is
removed as well.
Some time loop stuff was missing in the doobly-doo, the init() method
of the well model was not called and there was the slightly deeper
issue that the initial solutions where not calculated on restarts
which breaks everything that relies on them. (at the moment, that's
everything which is related to non-trivial boundary contitions.)
