Description

A general solver backend allowing arbitrary preconditioners and solvers.

This class is used as a base class for specific solver-preconditioner combinations. Several parameters from the group LinearSolver are read to customize the solver and preconditioner:

• Verbosity: determines how verbose the linear solver should print output.
• MaxIterations: the maximum number of iterations for the linear solver.
• ResidualReduction: the threshold for declaration of convergence.
• PreconditionerRelaxation: relaxation parameter for the preconditioner.
• PreconditionerIterations: usually specifies the number of times the preconditioner is applied. In case of ILU(n), it specifies the order of the applied ILU.
