Calling wells()->number_of_wells on nullptr causes segmentation fault. This
occurs when running a deck without wells. Allowing WellsManager::init to
continue for decks without wells enables the well struct to be set.

The wells, FIP and initial output of NNCs is still handled
by code in opm-simulators. The plan is to move more of the
functionality to ebos.
All tests pass and MPI restart works
it seems like most build systems pass a -DHAVE_CONFIG_H flag to the
compiler which still causes `#if HAVE_CONFIG_H` to be false while it
clearly is supposed to be triggered.
That said, I do not really see a good reason why the inclusion of the
`config.h` file should be guarded in the first place: the file is
guaranteed to always available by proper build systems, and if it was
not included the build either breaks at the linking stage or -- at the
very least -- the runtime behavior of the resulting libraries will be
very awkward.
if PETSc is not available, the .cpp file will compile fine because it
will be reduced to be empty, but trying to include
LinearSolverPetsc.hpp in this case will result in an error.
This is quite a hack: Even though energy is not a "phase" and it is
also not considered in MaxNumPhases and pu.num_phases because this
would break a lot of assumptions in old code, it is nevertheless
assigned an "canonical index" that can be translated "active index"
via PhaseUsage::phase_pos[]. This awkwardness is needed because much
of the legacy OPM code conflates the concepts of "fluid phase" and
"conserved quantity" and fixing that issue would basically mean an
almost complete rewrite of much of the legacy code. That said, the
same statement applies to polymer and solvent, but these are currently
handled as even more second-class citizens because they are not even
given a canonical index and also cannot be translated into an active
one.
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.
