Algorithmic Trends in CFD in the 1990’s for Aerospace Flow Field Calculationslopment in computer hardware resources and architectures has not only matched the explosive algorithm development but has indeed provided and continues to provide its impetus. Together the resources are now available for the numerical simulation of the flow about complex three dimensional aerospace

Advances for the Simulation of Compressible Viscous Flows on Unstructured MeshesHowever powerful this approach is it will be shown on a few examples that there is more to compressible viscous flows than this superposition. Along the way some of the recent findings relevant to Finite Volume and Finite Element Methods will be reviewed.

Some Challenges in Massively Parallel Computationseriously consider the use of modern ultrafast supercomputers. It turns out that the world of supercomputers is currently undergoing a major revolution which bids to accelerate the previously rapid rate of performance improvements while at the same time significantly improving price/performance.

Local Preconditioning of the Euler Equations and Its Numerical Implications solutions of the flow equations is to march in time from a suitable set of initial values, while applying the appropriate boundary conditions, until all time derivatives have become vanish-ingly small. Numerically this can be achieved, for instance, by applying an explicit finite-volume scheme over

Recent Advances in Lanczos-Based Iterative Methods for Nonsymmetric Linear Systems are now better understood, and so-called look-ahead variants of the Lanczos process have been developed, which remedy this problem. On the other hand, various new Lanczos-based iterative schemes for solving nonsymmetric linear systems have been proposed. This paper gives a survey of some of these r

Convergence Acceleration Algorithmss to reduce the number of iterations and the work required to obtain accurate solutions have always been in demand. Recent developments of modified and new techniques suitable for parallel computations are still in progress. The papers in this session present the state of the art and offer recommend

Issues in the Application of High Order Schemessome issues in the application of those schemes to time dependent problems are discussed. In particular we will review spectral shock capturing techniques and the asymptotic behavior of high order compact schemes.

Essentially Nonoscillatory Postprocessing Filtering Methodsrge oscillations in regions of sharp transitions. In this paper, we present a new class of filtering methods denoted by ENO-LS (Essentially Nonoscillatory Least Squares) which constructs an upgraded filtered solution that is close to the physically correct weak solution of the original evolution equ
