A Parallel Solver on a Dynamically Adaptive Overset Grid for Compressible Flow Problems
AerospaceThe overset grid adaptive method offers an efficient approach for the computational modeling of steady or transient three-dimensional compressible flow problems. When implementing this approach on parallel distributed memory computing systems, its scaling, load balancing, and partitioning must be addressed.
