Abstract
In a general flow simulation of the mechanical engineering, it is usually desired that the complicated grid is interactively generated and modified by using computer graphics as to remarkably increase the efficiency of the pre-procedure for the flow simulation.
In this paper, a routine system checking the adaptability of grid is developed to indicate any intersection, concentration, orthogonality, inclination and so on, and visual examples are displayed for the grid around the formula car with wheels.
The procedure is executed efficiently on a graphic computer of TITAN.
