the solution itself did not change, but yesterday's change of the
phase indices of the black-oil fluid system caused the fields to be
outputted in different order.

adaptation works, needs revision.
[dune-fem] using discrete function works.
some further work on grid adaptivity
dune.module: add dune-fem as a noptional dependency
Conflicts:

this is not needed anymore because the grid manager is no longer a
singleton and the grid is thus is always destructed before
MPI_Finalize() is called.
The most important issue was that PR#20 removed the possibility to use
a test driver script. In eWoms, this script is responsible for
(fuzzily) comparing the results of the test runs with reference
solutions, to test the simulators in parallel and compare the results,
and to make sure that the --help command continues to work as
intended.
the approach taken to bring this functionality back is to specify the
test driver script and its parameters using the new macro
'opm_set_test_driver(${DRIVER_COMMAND} ${DRIVER_DEFAULT_ARGUMENTS})'
before the first call to 'opm_add_test'. If no test driver is
specified, the binary is run 'naked', so nothing should change in this
case.
this patch requires the changes for opm-cmake to be merged first.
i.e., removing redundant namespace open- and closings due to the fact
that the property system now resides in the 'Ewoms' namspace instead
of in 'Opm', and making the headercheck work for all headers.
for the Richards model we can't use the CO2 injection problem because
this problem cannot be simulated by the Richards model. (Well,
strictly speaking the Richards model *can* simulate it, but it would
only produce garbage because the assumptions of the Richards model are
violated by that problem.)
this works by introducing a splice called "LocalLinearizerSplice". The
the current local linearizer (which is based on the finite difference
method) is the default and can be set explicitly by setting the splice
to "FiniteDifferenceLocalLinearizer", the new linearizer using
automatic differentiation can be selected by setting the splice to
"AutoDiffLocalLinearizer".
now the generic part of the update of the solution vector is done in
the base class and the derived classes can chose to only do the update
of the primary variables of the individual DOFs.
seems like the changes for vaporized oil caused it to be
different. Since SPE1 and SPE9 still deliver the same result and the
new reference solution is closer to what one would expect, the new
result is probably the correct one...
This reverts commit c6c271f3ee. After a
more thorough investigation, the cannonical name of these quantities
turned out to be "* formation volume factor"...
this also fixes the SuperLU backend with __float128 on Dune 2.4. The
problem is that due to some hacks within dune-istl, the AMG solver
can't be used because it calls the direct solver directly without an
option to disable this. (This could be fixed in a similar fashion as
the SuperLU backend by copying everything into data structures which
use 'double' before calling into ISTL, but this is a thing for another
time.)
... and use the parallel AMG solver for the CO2 injection problem.
this makes performance comparisions with Dumux much easier as the
solver performance should be more similar.
this helps to keep the core blackoil model code lean and mean and it
is also less confusing for newbies because the ECL blackoil simulator
is not a "test" anymore.
in case somebody wonders, "ebos" stands for "&eWoms &Black-&Oil
&Simulator". I picked this name because it is short, a syllable, has
not been taken by anything else (as far as I know) and "descriptive"
names are rare for programs anyway: everyone who does not yet know
about 'git' or 'emacs' and tells me that based on their names they
must be a source-code managment system and an editor gets a crate of
beer sponsored by me!
This code is required in the first place because opm-material always
specifies all parameters in terms of the wetting saturations while the
gas is the non-wetting phase in a gas-oil system.
this does not disrupt the block nature of the linearized matrix
(i.e. Dune::BCRSMatrix is still used), but if the number of auxiliary
equations is smaller than that of the "main" discretization, the
superfluous equations are padded. if the number of additional
equations are larger than that of the equation, additional DOFs are
added.
the biggest change is that it is now based on a new approach: the well
model now always calculates the bottom hole pressure for the full well
when asked for a source term. This change makes it possible to
implement cross flow within wells properly and should also make the
well model physically correct.
Also, the well model now uses the connection transmissibility factor
which makes it possible to use this quantity if it is specified by the
deck...
before this, gradients had the direction of the face between two
finite volumes, now they exhibit the direction of the two
FV-centers.
For axis-aligned grids the result is identical for interior faces, but
it is different for boundary faces or if faces are not
axis-aligned. This patch fixes the SPE9 troubles with anisotropic
permeabilities on tilted grids...
