Two of the most recent and important nonoverlapping domain decomposition methods, the BDDC method (Balancing Domain Decomposition by Constraints) and the FETI-DP method (Dual-Primal Finite Element Tearing and Interconnecting) are here extended to spectral element discretizations of second-order elli

The discrete systems generated by spectral or hp-version finite elements are much more ill-conditioned than the ones generated by standard low-order finite elements or finite differences. This paper focuses on spectral elements based on Gauss-Lobatto-Legendre (GLL) quadrature and the construction of

In this paper, we prove that the Algebraic A-FETI method corresponds to one particular instance of the original one-level FETI method. We also report on performance comparisons on an Origin 2000 between the one-and two-level FETI methods and an optimized sparse solver, for two industrial application
