This section configures the usage of an iterative solver for the linear matrix problem. One can select from a list of classical iterative solvers, see Solver. Matrix problems stemming from an Finite Element discretization suffer from a bad condition, leading to a poor convergence rate of a classical iterative solver. Therefore the an iterative solver should always be used alongside with a preconditioner which can be selected within this section as well.
