A motion graphic technique was utilized to visualize some computed flows around automobiles. Multi-block transformation and transfinite interpolation were used to generate the complicated grid systems. Unsteady flow fields were computed by the finite difference method using a third order upwind scheme. A mini supercomputer and a graphic work station, which were connected with each other through a local area network, were used for the grid generation and the flow visualization.It is concluded that the combination of the multi-block grid generation and the motion graphic flow visualization is very useful to analyze the unsteady flow. It enables us to understand the flows around the realistic automobile shapes with wheels, wheel wells and mud guards.
