Detailed Description

template<class TSparseSpace, class TDenseSpace, class TLinearSolver>
class Kratos::LineSearchContactStrategy< TSparseSpace, TDenseSpace, TLinearSolver >

A strategy for solving contact problems using a line search method.

This class is a specialization of the LineSearchStrategy class for contact problems. It implements a line search method for solving the contact problem, which involves finding the minimum of a scalar function along a search direction. The search direction is determined by the contact forces, and the scalar function is the norm of the residual vector. The class is templated on the sparse and dense linear algebra spaces, as well as the linear solver used to solve the linear system. It inherits from the LineSearchStrategy class and adds functionality specific to contact problems.

Template Parameters

TSparseSpace	The sparse linear algebra space.
TDenseSpace	The dense linear algebra space.
TLinearSolver	The linear solver used to solve the linear system.
