Automatic Computational Grid Generation Technology Supported by GIS

The computational grid generation is the prime procedure of hydromechanical numerical simulation. The results of generation affect the numerical simulation obviously. The manual grid generation methods were used for a long time. In this paper, the authors intend to apply the newly developing technology of Geography Information System (GIS) to the grid generation, use the computer to generate the numberical grid automatically, and discuss the integrated GIS-based numerical simulation environment and its function.
