i.e. it now supports stuff like MULTFLT in the schedule
section. Possibly, the MPI-parallel code paths need some fixes. (but
if the geology is not changed during the simulation, the parallel code
will do the same as before.)
the most fundamental change of this patch is that the
reference/pointer to the DerivedGeology object is made
non-constant. IMO that's okay, though, becase the geology can no
longer assumed to be constant over the whole simulation run.
to be able to determine the threshold pressure from the initial
condition it needs to be able to access the initial condition, i.e.,
the initial simulator state, material properties object and gravity
constant need to be passed to the thresholdPressure() function.

Since the refactoring to using opm-material a material law manager for
the global grid was used. This meant that the properties used for
elements of the local grid were wrong. With this commit we set up a
manager that is based on the local grid only.
1. Added new parameter group string: "solver_approach" which can take
the values {direct, cpr, interleaved}.
2. Hierarchy:
i If a value is set in the parameter group that takes absolute
presedence.
ii If the Eclipse input deck asks for CPR - you get CPR.
iii You get the flow default - currently interleaved.

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.
these are mostly stylistic: the function bodies of most new methods
have been moved to the _impl.hpp file and the Simulator classes are
now templated on the grid type, so it should be not too hard to switch
them to Dune::CpGrid.
since SimulatorFullyImplicitCompressiblePolymer is now a template, the
opaque pointer stuff is also removed and the contents of the .cpp file
basically became _impl.hpp. for SimulatorFullyImplicitBlackoilPolymer,
the opaque pointer stuff was removed for the same reasons as for
SimulatorFullyImplicitBlackoil.
the actual unification of code is not yet done, but this patch points
out the direction of where this will go.
Also note that some synchronization with the ordinary blackoil
simulator (FLOW) was necessary to make it compile.
Finnally, the parser currently likes to throw an exception (also for
the opm-polymer master) when eating the opm-data polymer test
case. This prevented me from properly testing this patch:
```

```
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".
As it turns out initializing the Geology on a distributed grid
result in wrong values for e.g. saturation. Therefore with this
commit we resort to initializing the global geology and distribute
it using communication.
Previously we used the size of the communicator within the CpGrid to check
whether we are running in parallel and need to redistribute the grid.
Unfortunately, this is MPI_COMM_SELF until we actually loadbalance and redistribute.
Therefore we now use the size of the MPI_Helper (i.e. MPI_COMM_WORLD) which
gives us the number of all available processes.
Note that the wrong behaviour was provoked with 656e5de331. Before that we
redistributed in any case which luckily included runs with more than 1 process.
Any argument that is not handled by the parameter parser will
be assumed to be a deck filename. Only one is accepted, and if
given, it will override any deck_filename=<something> on the
command line or in parameter files.
FYI:
The parameter parser handles arguments of the following types:
key=value (note no space around = or in strings)
parameterfile.xml
parameterfile.param
This makes some API changes to AutoDiffBlock.
- Add overload for the constant() constructor taking rvalue ref.
- Add overload for the variable() constructor taking rvalue ref.
- Make the function() constructor *require* rvalue refs.
- Add a swap() function.
The remaining changes in this commit are follow-ups especially
to the third change (adding std::move in many places), and
some removal of unnecessary block pattern arguments from calls to
the constant() static method.
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.
With now generic implementation of the initStateEquil in opm-core
we added the necessary grid helper functionlality for CpGrid and activated
the processing if the EQUIL keyword is there.
Previously BlackoilPropsDataHandle did hold a grid for sending
and receiving that were either not used or we could prevent their
usage. Therefore this commit removes them from the class and queries
all needed information from the property objects.
1) swatinit() is changed to setSwatInitScaling() to make it obvious that
we are modifying the props.
2) the descriptions of saturation and pc now makes more sense
3) the method is removed from the sibling class and the interface and
the type of new_props is changed from BlackoilPropsAdInterface to
BlackoilPropsAdFromDeck
5) The same modification is added to sim_fibo_ad_cp
The capillary pressure function in new_props is scaled to match the
capillary pressure function in props.
This is a temporary workaround while the simulator uses two different
property object.
Previously, we had to use two layers of overlap cells such the
innermost layer contains the rightvalues automatically (as it is
surrounded by internal edges). No we use communication to get
the correct values in the whole overlap region and one layer
suffices as it should.
With this commit we add the possibility to start with a global representation
of a simulator that is read on each process and afterwards this presentation
is redistributed among the processors together with the properties and
state data needed to initialize the simulation.
There still is no parallel well handling and no parallel output. But with the
equilibrium example of @dr-robertk and deactivated output we can already
perform parallel runs.
As with opm-core we use boost::any to provide additional
information about a parallel run. It is used to set a
ParallelISTLInformation object and and fill it with the
information obtained from a parallel Cpgrid.
Note that the simulator currently compiles sucessfully. Still,
we have to test the runs and do debugging.
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.
1) Add the possibility for the user to chose between local and global
coordinate permeability in the transmissibility calculations.
2) Trow for CpGrid
3) Add default for switch
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.
GCC 4.8 provides 'nullptr' in C++11 mode. That capability is
detected at configuration time and stored in <config.h> and we need
it when targeting Dune 2.2.1 to avoid diagnostics of the form
[...]/dune/common/nullptr.hh:27:1:
error: expected ‘;’ after class definition
} nullptr = {}; // and whose name is nullptr
^
[...]/dune/common/nullptr.hh:27:1:
error: qualifiers can only be specified for objects and functions
[...]/dune/common/nullptr.hh:27:3:
error: expected unqualified-id before ‘nullptr’
} nullptr = {}; // and whose name is nullptr
missing: the simulator using dune-cornerpoint. Once again, this is
because there is no good way to convert an intersection to a unique
global index (yet).
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...
The porv is computed if needed and the Eclipsestate will return false on
this test before it is called.
This commit applies the change to the sim_fibo_ad_cp.cpp
the goal is to make it faster on computers with many cores: The
easiest way to do this is to ensure that the longest running tests are
not taking too much time and that they need about the same time. Thus
this patch contains the following changes which limits the CPU time
taken by each test to about two minutes in debug mode on my machine:
- the water-air problem using the non-isothermal primary variable
switching model now uses an 16x16 instead of a 32x32 grid. as a
compensation it now runs for a year instead of 5000 seconds and the
global grid refinement is now tested.
- the end time of the lens problem ctests is now 3000 instead of
30000 seconds. The binary itself does not change at all.
- sort the tests in the CMakeLists.txt roughly in the order of their
required time. (this will cause ctest not having to wait for long
running test which were started late for too long.)
Currently, there are two abstract interface for the grids. One that
usually returns pods and arrays of them that also can be used by C
and is used also in opm-core, and one that returns Eigen datastructures
needed within opm-autodiff.
This commit adds a postfix ToEigen to those functions (faceCells, and
cellCentroidsZ) one could imagine to also return pods and arrays of them.
This should at least resolve the confusion about the two faceCells functions.
The next step will be issue #192Fixes#176
Also add some other features that have been added to sim_fibo_ad
but not to sim_fibo_ad_cp:
- (Un)Strict parsing parameter.
- EQUIL init (currently throws, since initEquil not yet made generic).
Total time will be written to walltime.txt, and single step times to
step_timing.txt (changed suffix from param to txt). This did not work
properly before this fix (step_timing file was overwritten each step).
This commit changes the API of class SimulatorFullyImplicitBlackoil<>
in order to support wells controlled by (total) reservoir voidage
volume rates. Specifically, we switch to holding a mutable Wells
object (backed by a std::shared_ptr<>) in class Impl rather than a
reference to a WellsManager. This allows dynamically updating rate
distributions and targets of individual well controls. That, in
turn, is a prerequisite to supporting ECL-style "RESV" control
modes--be it in prediction or history matching capacity.
While in the process of API changes, also prepare for the second
stage of "WCONHIST/RESV" support: Accept a ScheduleConstPtr that
holds the input deck's notion of the history matching vs. prediction
controls. We need to distinguish the two in order to support the
exact semantics of "WCONHIST/RESV".
Update SimFIBO<> clients accordingly.
it was used for debugging intersection mappers. to make this include
work, dune-cornerpoint must be available and that the intersection
mapper PR must be merged.
this means that all code which could potentially throw an exception is
moved to this method(). (In particular FluidSystem::init() proved
troublesome in the past.) Besides avoiding segmentation the faults
which stem from exceptions thrown in constructors, this also has the
advantage that simulations which spend a noticable amount of time to
initialize stop at the "correct" place, i.e. after the "Finish init of
the problem" message was printed by the simulator...
this regressed after time step index of the initial solution was
changed from 0 (actually, this was also 0 for the first time step...)
to -1 in b30af664.
The refactorisation of class FullyImplicitBlackoilSolver<Grid> to
defer transmissibility and pore-volume calculation to the client in
order to support multipliers (net-to-gross &c) accidentally ended up
removing all effects of gravity. This commit restores those effects.
this is required to implement pore volume and permeability multipliers
as discussed with [at]bska and [at]joakim-hove.
Note that this implies that the DerivedGeology class can't be
instantiated anymore if there is no EclipseState object. Thus all code
paths and tests that don't load a deck are removed by this patch. If
this is undesireable, there are two options: First, don't require
EclipseState for DerivedGeology which would imply to make the about 10
required multiplier functions part of the
BlackoilPropertiesAdInterface, or second, one can copy-and-paste the
DerivedGeology class as it was before this patch, derive from a newly
introduced DerivedGeologyInterface and pass DerivedGeologyInterface
objects to the simulator. IMHO, the second solution would be a bit
better but it would involve substantial overhead to implement and to
maintain it.
Anyway, in the mean time simulators cannot be instantiated without
decks.
this method checks that the difference in the storage terms before and
after a time step is the same as the accumulated fluxes over the
domain boundary plus the source terms.
... and actually use it for the lens problems. This seems to have been
disabled for debugging and later it was probably forgotten to turn it
on again. This led to some minor bit-rot in that code...
The reason for this is to be able to modify the tolerance according to
grid size: The NewtonTolerance parameter has been renamed to
NewtonRawTolerance and for the porous media models is divided by the
square root of the volume of the smallst finite volume in the grid to
get the final tolerance for the Newton method. This is necessary
because very large grids need to achive a higher volumetric accuracy
in the residual than very small ones...
basically the init() method was split into a finishInit() method which
fills the data structures allocated in the constructor with meaningful
data and into applyInitialSolution() which does just that (and no
more!)
"intensive" means that the value of these quantities at a given
spatial location does not depend on any value of the neighboring
intensive quantities. In contrast, "extensive" quantities depend in
the intensive quantities of the environment of the spatial location.
this change is necessary is because the previous nomenclature was very
specific to finite volume discretizations, but the models themselves
were already rather generic. (i.e., "volume variables" are the
intensive quantities of finite volume methods and "flux variables"
are the extensive ones.)
this basically means using Opm::EclipseState instead of the raw deck
for these keywords.
with this, property modifiers like ADD, MULT, COPY and friends are
supported for at least the PERM* keywords. If additional keywords are
required these can be added relatively easily as well.
no ctest regressions have been observed with this patch on my machine.

i.e. reading the grid properties from EclipseState instead of from the
raw deck. This requires that all deck files exhibit a GRID and a
SCHEDULE section or else EclipseState will throw in the constructor.
The following is changed in this commit:
- The constructor for NewtonIterationBlackoilSimple now takes
a parameter object instead of a linear solver.
- The fully implicit black-oil simulators can now use the CPR
preconditioning strategy (by passing use_cpr=true) or the
simple strategy (the default).
Note that as of this commit, the CPR preconditioning still has
not been implemented properly, and behaves just like the simple
strategy.
because "manager" sounds less religious than "creator" and the
GridCreators did all kinds of other stuff besides creating the grid.
this patch also gets rid of the static function inside these classes,
which should make them easier to understand...
this also comes with moving responsibilities around and some smaller
cleanups for the grid creation. (although grid creation could be
possibly done by the simulator now, the GridCreator concept has not
been abandoned, yet...)
Function GridManager::createGrdecl() generally allocates memory
(using std::malloc()) for the MAPAXES keyword data output of the
'grdecl' structure. Release those resources before leaving the
scope to prevent memory leak introduced in commit fdca540.
This commit switches to using the convenience method
GridManager::createGrdecl()
to construct a "struct grdecl" that can be passed directly into
CpGrid::processEclipseFormat(). The practical benefit is that we
get to leverage the opm-parser that's in active development rather
than the calcifying "EclipseGridParser" that will only become less
relevant in the future. We also don't parse the data twice.
Note: This is mostly compile tested. In the few actual tests I ran,
I got into trouble with internal assertions in processEclipseFormat.
That problem is not yet analysed.

This brings the "CpGrid support" branch up to date with respect to
recent changes in opm-autodiff master.
this makes the simulator quite a bit more maintainable: setting
USE_NEW_PARSER to 0 did not even compile after the the constructor for
the wells manager which took the old deck was removed last
week. Since, according to Atgeirr, SPE-1 is now producing exactly the
same results as before, it also does no longer make too much sense to
keep that code on life support...
These used to be needed to be enabled by the problem, but doing it in
the generic code is more fool proof and thus better.
On my laptop, volume variable caching caused the linearization time
for first time step of the isothermal vertex-centered CO2 injection
problem using the flash model go from 33.7 to 15.7 seconds, and
enabling thermodynamic hints in addition yielded a linearization time
of "only" 9.5 seconds. (that is for a debug build compiled with clang
3.3.)
this is implemented by extending the existing functionality for hints
and leads to a significant reduction of the volume variables updates
required. unfortunately, the performance with cached volume variables
is basically identical to the non-cached case, so they are disabled by
default...
anyway, this makes the thermodynamic hints code more robust and
cleaner, so it does not hurt to add it...
i.e., the simulator does not deal with any output operations
anymore. This makes sense because report steps are handled by
Opm::TimeMap and the constructor for the simulator already needs more
arguments than appropriate even without this...

In additions examples/sim_fibo_ad_cp.cpp was adapted to compile again.
i.e. it now uses Opm::EclipseState. This change required to re-add the
the epoch concept in some sense, but the loop variables now call it
"episode" which sounds less ethernal IMO.
this allows to retrieve the name of the problem before it is
instantiated. this is required to be able to print the "Initializing
problem" message at the correct point (i.e., before instantiating the
problem).
and some other minor changes. (if you need line search the issue is
probably caused a different problem and line search would be just a
work-around anyway.)
This should make things a much more robust, partially because now the
linear and the non-linear solvers use the same convergence criterion.
Also, this patch includes some collateral indentation improvements.
Since the SimulationTimer, EclipseWriter and WellsManager stuff has
not (yet?) been merged, the old parser is required to be around. Use
my parser-integrate-hacks_for_norne branches to test your stuff on the
Norne deck...
this required to abandon the "Epoch" stuff which the new parser does
not have (as well as the ECLIPSE file format knows nothing about
epochs). Handling well controls properly thus has to wait until Joakim
and Kristian finish refurbishing the WellsManager, so as a stop-gap
measure, only the first "epoch" is run.
