Development of a Common CFD platform-UPACS-

Abstract

This chapter explores how unified platforrn for aerospace computational simulation (UPACS) is used to overcome the increasing difficulty in recent computational fluid dynamics (CFD) code programming on parallel computers for aerospace applications and to accelerate the development of CFD technology by sharing a common base code among research scientists and engineers. UPACS, is a project aimed at developing a common CFD platform since 1998 at National Aerospace Laboratory. A common CFD platform “UPACS” that separates flow solvers from parallel processes has been developed in order to accelerate the CFD research and simulation program development, get better portability on various computers, and then easily share simulation programs and knowledge among CFD researchers and users. The UPACS solver can effectively simulate flows around complicated geometries with multiblock structured grids using some assisting tools for the UPACS. The UPACS continues its evolution to become a better CFD based tool.
