Detailed Description

template<typename TDomain, typename TGridFunction>
class ug::SmallStrainMechanics::ContactSmallStrainMechanics< TDomain, TGridFunction >

Contact conditions for small strain mechanical applications.

Begin of the considering contact conditions in a structural mechanical model for small strains. This implementation is based on active sets.

Still work in progress. A first introductive work for active sets and Lagrange multiplier can be found in:
