Viscous Modeling for Automated Flow Simulation

Existing Computational Fluid Dynamic solutions suffer from several major limitations which prevent widespread use within the scope of complex aerospace flow situations, specifically, the area of weapons development. These limitations include requiring significant model setup time, requiring skilled labor to generate the underlying computational grid, and requiring extensive computational resources to construct large models. In response to these issues, the proposed solution is to utilize a novel Meshless method that promises to eliminate the need for complicated meshing procedures which demand time and labor to complete. The success of this project will have significant impact on aerospace design by the Navy, as it will remove the tedious mesh generation and shift the focus to more important tasks such as solution analysis and design optimization. Furthermore, this technique is perfectly suited for recursive Cartesian based grid generation schemes which allow for highly automated, adaptive, and efficient solutions. In this project the feasibility of an adaptive octree grid generation scheme and Meshless flow solver will be determined. Its success will lay the foundations for Phase II efforts where a turn key CFD package will be developed, which would allow designers to seamlessly transition from CAD model to CFD solution.
