Abstract

In this paper, the bisection of the local mesh refinement in self adaptive finite element is applied to the obstacle problem of elliptic variational inequalities. We try to find the approximated region of the contact in the obstacle problem efficiently. Numerical examples are given for the obstacle problem.
