6e31c77234 Add more AMG options to allow setting from JSON. 2020-11-26 15:37:50 +01:00

d83ae17e5b Always accumulates data in AMG to 1 process on coarse levels. 
In OPM the matrix graph might be unsymmetric as we do not store
the full sparsity pattern for copy rows but only the diagonal.
Unfortunately, DUNE assumes that matrices from finite elements and
finite volumes have a symmetric sparsity pattern for copy rows to
and uses this assumption to create the graphs for PTScotch/ParMETIS
more easily. But PTScotch/ParMetis assume a symmetric graph.

9019a52937 Use enable_if on comm constructor parameter. 
As this is the one we want to check.

b016a1a714 [FlexibleSolver] active CPR if UseCpr is true and adjust maxIter. 
If no LinearSolverConfiguration is specified but UseCpr is true we
use cpr_quasiimpess. If the user does not specify the maximum
iteration number we use 20 for cpr.

2388a9b551 Added simple defaults for flexible solver: current options added ilu0, cpr_quasiimpes, cpr_trueimpes, file (genneal configuration) 
This commit 0c62c8442 cherry-picked and slightly cleaned up and
adapted to recent changes.

a76b19d95a Make FlexibleSolver feature-complete. 
In particular:
 - Add parallel solvers and preconditioners.
 - Add the update() interface to preconditioners, and use it with CPR.

ec498086a6 Add flexible solver and preconditioner infrastructure. 
Also use it in flow_blackoil_dunecpr.cpp. Adds new command-line parameter,
--linear-solver-configuration-json-file, to read linear solver config from
JSON-format file at runtime.
