the in-file lists of authors has been removed in favor of a global
list of authors in the LICENSE file. this is done because (a)
maintaining a list of authors at the beginning of a file is a major
pain in the a**, (b) the list of authors was not accurate in about 85%
of all cases where more than one person was involved and (c) this list
is not legally binding in any way (the copyright is at the person who
authored a given change, if these lists had any legal relevance, one
could "aquire" the copyright of the module by forking it and removing
the lists...)
the only exception of this is the eWoms fork of dune-istl's solvers.hh
file. This is beneficial because the authors of that file do not
appear in the global list. Further, carrying the fork of that file is
required because we would like to use a reasonable convergence
criterion for the linear solver. (the solvers from dune-istl do
neither support user-defined convergence criteria not do the
developers want support for it. (my patch was rejected a few years
ago.))
This makes eWoms multi-discretization capable. Along the way, this
fixes some bugs and does a medium sized reorganization of the source tree.
This is a squashed patch of the following commits:
--------
1st commit message:
add initial version of the element centered finite volume discretization
currently, it is a misnomer as it is just a copy of the vertex
centered discretization plus some renames...
--------
2nd commit message:
rename [VE]cfvModel -> [VE]cfvDiscretization
--------
3rd commit message:
ecfv: prelimary changes required to make it compile
but not work yet...
--------
4th commit message:
Rename *FvElementGeometry to *Stencil
"Stencil" seems to be the standard expression for this concept...
(also, it is not specific to finite volume methods and is shorter.)
--------

refactor the stencil class for the element centered finite volume discretization
--------
6th commit message:
ECFV: some work on the stencil class

--------
16th commit message:
ECFV: make it work to the point where it can write out the initial solution.
--------
17th commit message:
ECFV: make it work
the local residual/jacobian needed some work in distinguishing primary
and secondary DOFs and there was an minor issue with the serialization
code.
for some reason, it seems still not correct. (-> convergence is too slow.)
--------

VCFV: make it compile for the black oil model again
--------
19th commit message:
VCFV: make it compile with the remaining models again

unify what's to unify for the [EV]CFV properties
--------
46th commit message:
make the method to calculate gradients and values at flux approximation points changeable
Currently, this is used by the vertex centered finite volume method to
be able to use P1-finite element gradients instead of two-point
ones...
--------
47th commit message:
make the restart code work correctly, use the correct DofMapper for VCFV
--------
48th commit message:
actually use the gradient calculator in a model
the immiscible model in this case
--------
49th commit message:
move some files around to where they belong, use the new gradient calculation code in all models
TODO: proper handling of boundary gradients
--------
50th commit message:
fix the stokes model
currently it only works with the vertex centered finite volume
discretization, but the plan is to soon move it to a staggered grid
scheme anyway...
--------
51st commit message:
move all models back to using the vertex centered finite volume discretization by default
--------
52nd commit message:
models: some variable renames and documentation fixes
- scv -> dof
- vert -> dof
- vertex -> dof
- replace 'VCFV'
- fix some typos
--------
53rd commit message:
don't expect UG anymore
since it is quite non-free and hard to get. we now use ALUGrid instead!
--------
54th commit message:
temporarily disable jacobian recycling
--------
55th commit message:
fix writing/reading restart files using the generic code
--------
56th commit message:
fix bug where fluxes were only counted once in the stencil
this only affected the vertex centered finite volumes discretization...
--------

boundary gradients: use the center of the sub-control volume adjacent to a boundary segment
--------
58th commit message:
make it compile on GCC
--------
59th commit message:
get rid of most hacks
for this, partial reassemble and jacobian recycling was brought
back. For the this and the remaining stuff the main trick is the
introduction of the GridCommHandleFactory concept which constructs
communication handles suited for the respective spatial
discretization...
--------
60th commit message:
fix a few annoying bugs
first, default the convergence criterion for the linear solver did not
honor the initial residual which lead to linear solver breakdowns,
then some debugging code was left in the discrete fracture model and
then there was a bug in the TP gradient approximation class...
this has the consequence that we need a new reference solution for the
discrete fracture problem...
--------
61st commit message:
iterative linear solver: remove the code for the non-default convergence criteria
--------
62nd commit message:
provide the FE cache instead of the local FE
this fixes a segfault in the stokes model caused by the fact that the
local FE was not initialized at this point.
--------
63rd commit message:
(Navier-)Stokes: fix bug due to the transition to unit normals
now, all tests pass for this branch. The only things which need to be
fixed are some annoying performance regressions compared to master and
some bug in the splices feature of the property system...
--------
64th commit message:
some fix for the local residual of the immiscible model
--------
65th commit message:
Navier-Stokes: implement SCV center gradients
There seems to be a bug in the previous implementation (the jacobian
inverse transposed is evaluated using the local, not the global
geometry), so the reference solution for the stokes2c test problem has
also been updated...
--------
66th commit message:
remove the ALUGrid specialization of the LensGridCreator and the YaspGrid one for the fingerproblem
using different grid seems to sometimes cause a different vertex
order, which in turn causes the respective test to fail if the
reference solution was computed using the other grid...
--------
67th commit message:
VCFV: use the correct BorderListCreator
this makes MPI parallel computations work again. apart from
performance regressions, this branch does not exhibit any known
regressions compared to master anymore...
--------
68th commit message:
make verything compile with the element centered finite volume discretization
except the Navier-Stokes and the two-phase DFM models, of course...
--------
69th commit message:
minor fixes
- make the navier-stokes model slighly more generic by using the
proper (in,ex)teriorIndex() methods on sub-control volumes
- make the signature of the calculateValue() template method of the
common two-point gradient approximator match the one of the vertex
centered finite volume one
--------
70th commit message:
fix fallout from the Big Rebase
--------
71st commit message:
ECFV: some bugs in the boundary
--------
72nd commit message:
make computeFlux() compute area-specific quantities
--------
73rd commit message:
fix more bugs in the element centered FV discretization
now eWoms should match Dumux pretty closely...
--------
74th commit message:
coalesce the common code of the multi phase porous medium models into "MultiPhaseBaseModel"
--------
75th commit message:
update reference solutions
these were changed because of the screw-up with the area of boundary
segments...
--------
76th commit message:
rename "ImplicitBase" to "FvBase"
because in eWoms, everything is implicit and these are currently the
base classes for all finite volume discretizations.
--------
77th commit message:
make the spatial discretization selectable using a splice
This requires an opm-core with a the patches from
https://github.com/OPM/opm-core/pull/446 merged...
--------
78th commit message:
rename the properties used for splices to *Splice
--------
79th commit message:
move the files in 'tests/models' to 'tests'
since 'tests' was empty except for the 'models' subdirectory...
--------
80th commit message:
improve and fix the tutorial
--------
81st commit message:
remove the -fno-strict-aliasing flag from the provided option files
seems like recent versions of Dune have been adapted...
--------
82nd commit message:
also compile all CO2 injection simulations using the element centered finite volume discretization
--------
83rd commit message:
PVS model: make it work properly with the element-centered finite volume discretiation
because DOF != number of vertices
