Our goal is to develop an efficient implementation of the BDDC method, which could be used fo solution of large problems of today's computational mechanics and structural analysis. A parallel approach is necessary for the usage of powerfull computer resources. We present results of computations of practical problems in 3D elasticty.

Balancing Domain Decomposition with Constrained Energy Minimization (BDDC) derives benefit from the synergy effect between substructuring methods and multigrid approaches to preconditioning. It has been shown in several studies, that this method posseses very good properties and is competitive with FETI and FETI-DP methods, which could be mentioned among leading algorithms in the field of unstructured meshes decomposition for solving partial differential equations.
