This research focused on a class of domain-decomposition techniques for solution of problems in Computational Fluid Dynamics using advanced vector and parallel processors. Particularly considered are finite-element schemes and natural-element schemes and use of the natural-element partition of the domain to construct the decomposition algorithm. This then fits conveniently into the usual framework of finite-element calculations in which the primary loop is the independent calculation and assembly of element-matrix and vector contributions. By recasting the conjugate gradient method at this level, the system matrix need not be assembled and the intensive matrix-vector product step can be completely parallelized. These ideas constitute a major departure from traditional finite element schemes, and it is felt these efforts are a major new development that will strongly influence the technology.
