this is intended to be used for ECLIPSE saturation curves, but the
code is more generic. (Be aware that using cubic splines for the
interpolation between sampling points is probably a better choice in
most cases.)
- add methods to calculate the derivatives of the capillary pressures
and relative permeabilities with regard to the phase saturations,
temperature, absolute pressure and phase composition
- extend the unit test to enforce the above
- make the NullMaterial conform to the API and add it to the unit test
- introduce Opm::NullMaterialTraits for material laws that don't use
any phase indices
They are now all generic capillary pressure laws, but with some
additional methods to make working with them easier. For this reason,
they have been moved up one directory to opm/material/fluidmatrixinteractions
Also, a unit test which ensures that all capillary pressure laws
conform to their respective APIs has been added.
this was due to a missing initialization of the MPI. Because
MPI_Finalize should probably called even if the program is aborted due
to an exception, this is done using a helper class. (which does the
same job as Dune::MPIHelper, but is much simpler.)
basically the only Dune thing which is still used are the FieldVector
and FieldMatrix classes used by some constraint solvers. Until
something similar goes into opm-core, opm-material must depend on
dune-common...
