Interpolation between Cartesian and Curvilinear Grids Using Parallel Computation

Abstract

The importance of accurate and fast interpolation algorithm is growing up for helicopter simulation with multi-body configuration, because of complex movement of helicopter including rotor-rotation and flight motion. In this paper, interpolation algorithms are implemented for two different grids, Cartesian grid and curvilinear grid, of which the overlapped grid system consists. New searching algorithms are proposed to make full use of (1) the characteristics of Cartesian grid, (2) special geometric configuration of helicopter, and (3) load balancing in parallel computation. By applying these searching algorithms, efficient massive computation can be achieved for the helicopter configuration.
