Advanced Overset Grid Methods For Massively Parallel Rotary Wing Computations

Abstract

Parallel overset grid assembly techniques have recently been implemented in the U.S. Army Helios software for rotorcraft aeromechanics simulations. The work presented in this report describes an innovative active load balancing algorithm that improves the robustness and scalability of domain connectivity operations. Another aspect of this works in to development of conservative overset grid methods. Preliminary results in 2-D for cell-centered unstructured grid show feasibility of this approach and improvements in predictions when compared with conventional overset grid approaches.
