Abstract: CFD numerical simulation system is a combined technology of CFD flow solving, grid generation, data visualization and networking. This paper described an integrated interactive CFD simulation system for subsonic, transonic and supersonic flows, running in a network environment. This system can easily integrate various flow solvers for complex configurations, including panel method codes, potential flow codes, and codes for Euler and Navier Stokes equation through its unified data interface. This paper also described the development of the system architecture, the software structure, the pre processor for geometry and grid generation, the powerful flow field solvers, and the advanced data visualization subsystem.

Key words: CFD, grid generat ion, data visualizat ion, data interface
