The modeling of the mechanical structures with large number of degrees of freedom (DOF) was in the past the problem of the machine time and disk space. On the today’s hardware it is possible to solve 106 equations without big problem. But if the algorithm requires the iteration approach (nonlinearities) or solving the dynamic problem via direct numerical integration this could take long time and large disk space. In this case the domain decomposition could give the advantage. The paper describes the solution of the large mechanical structure of the bearing with rather high number of contact pairs using so called “super-elements”.
