      [solver] Remove TypeTag dependency of linear solver · ac426f91
      Timo Koch authored 
      This patch reduces dependencies and makes usage of linear solvers more flexible, i.e. for two problems with different typetag

* Linear solvers don't need type tag anymore, in fact they don't need any template params
* the preconditioner block size is now provided for the solve method (see e.g. staggered newton controller)
* the amg has a convencience alias using a TypeTag but is "independent" through indirection via the traits

      [amg] Decouple AmgTraits from property system · a794364e
      Timo Koch authored 
      The Amg properties where defined in an amg header for other discretization TypeTags.
This leads to a lot of dependencies because files from all model types where included.
Now the includes are reduced to property forward declarations and disc methods.

      [AMGBackend] fix AMGBackend for sequential grids and HAVE_MPI == 1 · 21c2b3d8
      Bernd Flemisch authored 
      So far, the AMGBackend only worked for sequential grids if HAVE_MPI
was 0. This was due to the fact that AmgTraits distinguished between
parallel and sequential by evaluating HAVE_MPI. If HAVE_MPI was 1
but the Grid was sequential, this lead to compiler errors for the
constructor calls of the Communicator, LinearOperator and
ScalarProduct.

Do this properly now by using Dune::Capabilities for distinction
between the sequential and parallel case. For Dune 2.4, the
capability isParallel has to be used, while for Dune 3.0, it is
canCommunicate. The correct AmgTraits and constructor calls are
chosen by template specialization.

This solves FS#300.

      [el2p] parallelize the el2p model · 8c450823
      Bernd Flemisch authored 
      So far, the el2p model did not run in parallel, since our parallel
solvers assume a certain ordering of the degrees of freedom. This patch
mainly introduces an AMG backend that is tailored to the el2p model. It
simply reorders the linear system by copying from the original system,
passes the reordered system to the original AMG backend, and
reorders/copies the result back. This could be achieved more
efficiently and with less memory usage by already reordering the dofs
inside the el2p model or by adapting the AMG backend. Since the
performance impact appears to be minimal, we decided to keep the current
simple solution and try a better one once we need it.

      [amg] clean up the AMG backend · 97575a22
      Bernd Flemisch authored 
      - The properties "AMGPDELabBackend" and "AMGLocalFemMap" are unified to
  "AmgTraits". Since they appear to have been used only internally and
  deprecation is technically difficult, no deprecation is made.

- Remove setting of the property "SolutionVector", since it only resets
  the defaults.

- Deprecate the classes "SeqAMGBackend" and "ScaledSeqAMGBackend". The
  "AMGBackend" already distinguishes between serial and parallel
  settings. The scaling should be done for the residual already.

- Deprecate the class "P0LocalFiniteElementMap" which was only used for
  the PDELab-based backend.

- Remove occurrences of "PDELab" in the comments.
