Development of Visual Computing Systems for Fluid Dynamics Simulations

Visual computing is an advanced simulation in which the intermediate computed results are visualized during the computations. In the present paper, two visual computing systems aiming for the practical research use were developed for the fluid dynamics simulations. One is a system for rather small scale simulations, i. e. two-dimensional computations or scheme developments, and runs on a single graphics workstation. The other is a system for small to large scale simulations, i.e. three-dimensional computations, and runs on a system of one graphics workstation and one CPU server. Both systems are machine-independent. Several examples including the elapsed time measurements of the simulation, the graphics and the data transfer show various use of the visual computing, the achievement of the designed features of the present systems and the advantage of the visual computing to the "postprocess" visualization.
