Abstract :
In this paper, a new dual-primal domain decomposition method referred to as the FETI-DPEM2 is proposed, which retains all the advantages of the FETI-DPEM (dual-primal finite element tearing and interconnecting) such as the construction of the global coarse problem and the explicit interface equation that can be solved by Krylov subspace method, while significantly improving the performance in the high-frequency region.
