Parallel Simulation of Moving Boundary Flow Using Overset Adaptive Cartesian/Prism Grids and DES

Abstract

Two major tasks have been undertaken in this year: the development of OverCart- the overset Cartesian/prism grid generator and adaptor, and the enhancement of the flow solver to handle moving overset Cartesian/prism grids. Satisfactory progresses have been made in both tasks, and we are on target and within budget to accomplish all the planned research and development efforts. More specifically, the following activities have been carried out from March 1 to September 30, 2004:1. An extensive effort has been made in making the prism grid generation more robust. A comprehensive literature search was carried out to identity the most recent development in this area, and new algorithms are designed and tested. As a result, the prism grid generation algorithm is much more robust, and was capable of tackling vet) complex geometries; 2. The hole cutting and donor cell finding have been implemented in the OverCart software. Octree-based and ADT tree-based algorithms have been employed to speed up the search operations.
