CACTUS CFD Toolkit: Combination of Aerodynamic Solver with Advanced Computing Technologies

Abstract

Cactus[1] is a general-purpose, modular PSE(Problem Solving Environment) designed for scientists and engineers. Since 1995, the base framework has been developed and mainly applied for large scale astrophysics simulations[2]. From those researches, Cactus proved to be a valuable tool for scientific and engineering applications that are tightly coupled, have regular space decomposition, and huge memory and processor time requirements. Currently, Cactus is under the progress of being applied to various studies including CFD(Computational Fluid Dynamics)[3], quantum relativity, chemical reaction and EHD(Electro-Hydro-Dynamics). Especially for CFD simulations, aerodynamicists at 'Seoul National University', 'KISTI Supercomputing Center' and 'KAIST' have been collaborating to make a compressible CFD toolkit working on the Cactus framework. Present paper introduces the current status of a CFD toolkit on the Cactus.
