      [cornerpoint] add capability to use cornerpoint grids · 35f692be
      Bernd Flemisch authored
      Introduce a grid creator that reads from a Petrel output / Eclipse input
      file and generates a CpGrid that is offered by the OPM module
      dune-cornerpoint. Enhance the fully-implicit cell-centered models to be
      able to deal with cornerpoint grids, test the functionality. This patch
      consists of several parts:
      - patches/ and dune.module: the CMake buildsystems from Dune and OPM are
        not compatible. The patches change some CMake files in the required
        OPM modules opm-parser, opm-core and dune-cornerpoint in such a way
        that those modules can serve as a dependency for Dumux. In addition,
        some specific CMake options have to be passed to dunecontrol. See
        patches/README for details.
      - dumux/io/: defines the CpGridCreator which behaves like any other grid
        creator that reads from a file. In addition, it offers the Eclipse
        input deck in form of a static function deck(). This deck can be used
        to extract further simulation parameters, most prominently porosity
        and permeability values.
      - dumux/implicit/cornerpoint/: changes some of the cell-centered
        classes to be able to deal with a CpGrid. The changes in the
        ElementVolumeVariables and the FVElementGeometry are minor and
        required by the facts that a CpGrid doesn't offer codim-1/2 entities
        and that the geometries don't offer local-to-global mappings. The
        changes in the DarcyFluxVariables are made for enhancing the
        robustness of the two-point flux approximation by forcing the
        inter-element transmissibilities to be positive.
      - test/implicit/2p: runs a fully-implicit two-phase immiscible model on
        a CpGrid. An element index with an injection rate can be given in the
        input file. The grid provided in grids/ consists of only four
        elements, but exhibits typical cornerpoint features like a
        nonconforming situation and general hexahedrons. A more realistic grid
        will be provided in dumux-lecture soon.
