Detailed Description

Provides all unmodified linear solvers from dune-istl.

To set the linear solver, use

template<class TypeTag>
struct LinearSolverWrapper<TypeTag, TTag::YourTypeTag>
{ using type = Opm::Linear::SolverWrapper$SOLVER<TypeTag>; };

The possible choices for '$SOLVER' are:

• Richardson: A fixpoint solver using the Richardson iteration
• SteepestDescent: The steepest descent solver
• ConjugatedGradients: A conjugated gradients solver
• BiCGStab: A stabilized bi-conjugated gradients solver
• MinRes: A solver based on the minimized residual algorithm
• RestartedGMRes: A restarted GMRES solver

Chosing the preconditioner works in an analogous way:

template<class TypeTag>
struct PreconditionerWrapper<TypeTag, TTag::YourTypeTag>
{ using type = Opm::Linear::PreconditionerWrapper$PRECONDITIONER<TypeTag>; };

Where the choices possible for '$PRECONDITIONER' are:

• Jacobi: A Jacobi preconditioner
• GaussSeidel: A Gauss-Seidel preconditioner
• SSOR: A symmetric successive overrelaxation (SSOR) preconditioner
• SOR: A successive overrelaxation (SOR) preconditioner
• ILUn: An ILU(n) preconditioner
• ILU0: A specialized (and optimized) ILU(0) preconditioner
