The domain decomposition method (DDM) is a major solution algorithm for large-scale finite element analyses. The balancing domain decomposition (BDD) method is an efficient substructuring-based iterative linear solver. In this chapter, a method by which to incorporate a set of linear multipoint constraints (MPCs) into the BDD method is described.
