FAST: a multi-processed environment for visualization of computational fluid dynamics

摘要: Three-dimensional, unsteady, multi-zoned fluid dynamics simulations over full scale aircraft is typical of problems being computed at NASA Ames' Numerical Aerodynamic Simulation (NAS) facility on CRAY2 and CRAY-YMP supercomputers. With multiple processor workstations available in the 10-30 Mflop range, we feel that these new developments scientific computing warrant a approach to design implementation analysis tools. These larger, more complex create need for visualization techniques not possible with existing software or systems as this writing will change supercomputing environment, hence methods employed, evolve even further.Visualization computational aerodynamics requires flexible, extensible, adaptable tools performing tasks. Flexible means ability handle diverse range problems. Extensible interact all levels hierarchy, either through built-in functionality custom "plug-in" modules. Adaptable adapt hardware configurations use modular structured programming methods, graphics library standard, common network communication protocols (like UNIX sockets) distribution processing.This paper discusses FAST (Flow Analysis Software Toolkit), an system mechanics based approach.
