Finite Element Domain Decomposition Procedures
摘要
A detailed explanation (including examples) of different finite element algorithms based on “divide-and-conquer” strategies (such as classical substructuring method, FETI-D, FETI-DP methods) is presented in this chapter. Major subtopics including the generalized/pseudo-inverse, preconditioned conjugate gradient (PCG) algorithm and mixed direct-iterative solvers are also discussed in this chapter.
