Two level FETI method for transient problems
Original language description
In this paper we deal with a variant of FETI (Finite Element Tearing and Interconnecting) domain decomposition method for transient problems of linear elasticity. The basic idea of this method is based on the standard FETI-DP approach, but the implementation is more close to classical FETI/TFETI method. This method can be viewed as two level FETI method. The effective stiffness matrices are assembled for floating subdomains and the continuity of the solution across the interfaces is enforced by two sets of Lagrange multipliers. The first set enforces the continuity at the "corner" nodes. The continuity on the rest of the interface is obtained within the iteration process as in standard approach. The behavior of the proposed method is demonstrated on academic benchmark implemented within the MatSol library.
