A Preconditioner for Substructuring Based on Constrained Energy Minimization


A preconditioner for substructuring based on constrained energy minimization concepts is presented. The preconditioner is applicable to both structured and unstructured meshes and offers a straightforward approach for the iterative solution of secondand fourth-order structural mechanics problems. The approach involves constraints associated with disjoint… (More)
