Detailed Description

template<class TSparseSpace, class TDenseSpace>
class Kratos::ResidualBasedIncrementalAitkenStaticScheme< TSparseSpace, TDenseSpace >

A scheme for the solution of a problem using Aitken iterations.

Aitken's method intends to improve convergence by introducing a relaxation factor in the update of the solution after each iteration.
