An analysis of performance enhancement techniques for overset grid applications [PDF]
Proceedings International Parallel and Distributed Processing Symposium, 2004 The overset grid methodology has significantly reduced time-to-solution of high-fidelity computational fluid dynamics (CFD) simulations about complex aerospace configurations. The solution process resolves the geometrical complexity of the problem domain by using separately generated but overlapping structured discretization grids that periodically ...
