Detailed Description

Provides wrapper classes for the (non-AMG) preconditioners provided by dune-istl.

In conjunction with a suitable solver backend, preconditioner wrappers work by specifying the "PreconditionerWrapper" property:

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
