Detailed Description

Implements a generic linear solver abstraction.

Chosing the preconditioner works by setting 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: An ILU(0) preconditioner. The results of this preconditioner are the same as setting the PreconditionerOrder property to 0 and using the ILU(n) preconditioner. The reason for the existence of ILU0 is that it is computationally cheaper because it does not need to consider things which are only required for higher orders
