The Iterative Group Implicit (IGI) algorithm is developed for the parallel solution of general structural dynamic problems. In this method the original structure is partitioned into a number of a subdomains. Each subdomain is solved independently and therefore concurrently, using any traditional dir

The accuracy of a new class ofconcurrent procedures for transient finite element analysis is examined. A phase error analysis is carried out which shows that wave retardation leading to unacceptable loss of accuracy may occur if a Courant condition based on the dimensions of the subdomains is violat
This paper studies and compares the domain partitioning algorithms presented by Farhat, Al-Nasra and Nguyen, Malone, and Simon/Hsieh et al. for load balancing in parallel finite element analysis. Both the strengths and weaknesses of these algorithms are discussed. Some possible improvements to the p
