This patch refactors (hopefully) all parts of opm-core that are needed
by the fully implicite black oil solver in opm-autodiff and that inherently
relied on UnstructuredGrid.
We added a new simple grid interface consisting out of free functions
that will allow us to use CpGrid without copying it to an UnstructuredGrid
by the means of the GridAdapter. Using this interface we have add methods that
allow specifying the grid information (global_cell, cartdims, etc.) wherever
possible to prevent introducing grid parameters for the type of the grid.
Unfortunately this was not possible everywhere.
this simplifies the template meta programming a bit. (Which does not
mean that it suddenly gets easy.) The main motivation for this work is
to make the splices feature work properly which allows eWoms to
properly select the spatial discretization at any point.
Further, the number of type tags a node can inherit from now is truely
unlimited thanks the the generic tuple reversal class provided by
https://sydius.me/2011/07/reverse-tuple-in-c/ . (before, the maximum
number of nodes from which a type tag could inherit was 11, so this
limitation did not really matter in practice.)
Add new function is added that computes saturation from surface volumes
solving z = As for each cell. This function is used to compute an
intial guess to the saturations in initState_impl.hpp.
I originally wanted to make share_obj a class so that I could hide the
helper function, but it turned out that I needed a function after all
since a function template can be inferred from the parameters but the
type cannot from the constructor.
By returning a shared_ptr directly, the compiler can do return object
optimization.
The template function share_obj let you pass regular references
as shared pointers, which makes it easy (perhaps too easy) to quick-
fix old code which pass references and have stern warnings about the
lifetime rules of the objects in the documentation section instead.
also, extend the unit test for it. (*phew* that was much more fun than
appreciated because of all the index shifts. I'm still not 100% sure
that everything works in all corner cases, but at least my confidence
is at 95%.)
most of these issues are fallout from the conversion of the spline
class from a moments (second derivative) based approach to hermite
base functions:
- the second and third derivatives where incorrect, and the third
derivative was not available in the public interface.
- The unit test did not check the derivatives
- The coefficients for the monomial basis were off by the factors
stemming from the derivatives
- The intersectIntervall_() method used std::max() instead of
std::min() at one place and still added the base offset for the x
values as indicated by Stoer
This should fix the common case where the curve is non-constant within
an intervall. I'm not really sure whether it's correct in all corner
cases, though.
this fixes the eWoms test case for the blackoil model which failed in
debug mode due to some asserts incorrectly triggering...
These functions are referred to from templates which may not be
instantiated. Since they were in an anonymous namespace they were
not reachable otherwise, and a warning is emitted. This only applies
to Clang; GCC consider them used.
If we make them static helper functions instead, the warning
disappears.
make all non-implementation headers includable without
preconditions. Also, this removes the GravityColumnSolver.hpp file,
because it tried to include a non-existing file and it was thus unused.
The OPM_THROW macro uses an internal symbol, 'oss', which is, strictly
speaking, in the client's namespace. Moreover, as the
"EclipseGridParseHelpers.hpp" header uses the same symbol, and for
similar purposes, this produces warnings at "-Wshadow" in GCC when
compiling that header.
Rename the macro's symbol to 'oss__' (double trailing underscore) to
reduce the likelihood of shadowing a previous definition.
