This project concerns the design of an interactive flow solver software technology. The novel aspects include the development of a network-compatible software environment for CFD, the focus on interactivity and real-time response, and the design of graphical user interfaces for scientific computation. The project objective is to develop a capability for interacting with a three-dimensional Euler solver in real-time. A successful effort will establish the possibility of building interactive CFD software for a CRAY-SGI-Ethernet-TCP/IP-UNIX-ARC3D combination.The software produced from this effort, combined with interactive grid generation software, will allow end users to significantly reduce the time spent in the CFD design cycle and provide scientists with a common numerical laboratory for CFD.interactive, three-dimensional, CFD, softwareSTATUS: Phase I Only
