A fully automated Chimera methodology for multiple moving body problems
A fully automated Chimera methodology has been developed in this study to provide geometric or stencil information required to facilitate inter-grid data communications. Chimera holes are cut automatically in each grid of an overset grid system based on whether the grid overlaps with non-penetrable surfaces (NPS) and/or blocked regions. The efficiency of the hole-cutting algorithm is boosted with search algorithms based on the state-of-the-art alternating digital tree (ADT) data structures. The automated nature of the hole-cutting algorithm is ideally suited for handling multiple moving body problems. Several cases, both steady and unsteady, are used to demonstrate the effectiveness of the methodology. Copyright (C) 2000 John Wiley & Sons, Ltd.
