Abstract

This chapter reveals that the analysis in the flowfield of the complex geometries has become practically important. Building the efficient computational algorithm which can analyze the flowfield around complicated shaped bodies brings a great contribution in engineering. Therefore, the purpose of this chapter is to develop an efficient parallel computational algorithm for analyzing the flowfield of complex geometries. In this approach, grid generation and the load balancing in parallel computing are very important factors. For the flowfield where two or more complicated shaped bodies exist, overset grid technique is used to avoid the difficulty of generating a single grid system over the complex field. However, when the number of overlapping grids increases, an efficient procedure is needed for exchanging information between grids; the chapter proposes an efficient treatment.
