Detailed Description

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

Convergence criteria for contact problems.

This class implements a convergence control based on nodal displacement and lagrange multiplier values. The error is evaluated separately for each of them, and relative and absolute tolerances for both must be specified.
