Demonstration of the Matsol Library Developed for the Efficient Solution of Contact Problems and its Comparison with Ansys

The goal of this contribution is to present the MatSol library developed for the efficient solution of large problems in contact mechanics. The MatSol solvers are based on FETI domain decomposition methods which are well known by their parallel and numerical scalability. The performance is illustrated on a model contact problem of the cantilever cube over the obstacle. Finally, we compare the MatSol solution with the ANSYS one of a simplified contact problem with Coulomb friction of the yielding clamp connection.
