Experiences with FETI-DP in a Production Level Finite Element Application

Introduction The need for predictive, qualified models of very complex structures drives the requirements for large scale structural analysis. Reduced testing in the nuclear weapons program is a driving factor at the DOE labs. In addition, more detailed models reduce the need for engineering approximation, improve accuracy and often simplify model construction. Uncertainty in model parameters (for example, variations in joint preloads) can require multiple analyses for evaluation of a structure. Salinas was designed to meet the needs of a very large scale, general purpose, structural dynamics analysis ([1] and [14]).
