Numerical Algorithms for Steady and Unsteady Multi-Disciplinary Simulation of Flight Vehicles

Industry is driven by the cost of man-power and time to market, and is still awaiting a versatile and reliable multi-disciplinary analysis code. The proposed JFLO software suite addresses many aspects that are still not totally resolved in current state-of- the-art CFD. It will enable optimal designs as well as the multi-disciplinary application of CFD for digital flight. The key elements of JFLO are : ease of use; broad analysis capability for 3D steady and unsteady applications for the entire range of speeds for low Mach to supersonic, high-resolution mesh-blind solution algorithms and CAD-blind surface reconstruction, mesh-and user-independent results via CAD-respecting mesh adaptation, fast solutions via advanced convergence acceleration techniques, and above all reliability and high accuracy. It weaves together technologies that have been recognized in their individual right: optimal control design, coupled CFD and CSD and automatic mesh optimization. Here they are brought together in a single package for the first time.
