Computational Fluid Dynamics (CFD) has been developed greatly through the progress of supercomputers and computational schemes. Various 3-dimensional analyses with large scales are carried out nowadays, of which the most famous is the flow around aeroplanes. There are seldom cases where the 3-dimensional unsteady flow results are dynamically shown, though the flow visualization is inevitable for understanding the flow field. Imcompressible viscous unsteady flow around a car is simulated. The third-order-upwind difference scheme is used in this simulation. The grid system is generated by using the multi block transformation. Computed pressure distribution on the surface agrees well with experiments. Typical vortical motions in the flow around the car are clearly visualized by the motion graphic system.
