Abstract :
A large-scale finite element simulation and modeling method for environmental flows is presented. The stabilized parallel finite element method based on SUPG/PSPG method was employed. The present method was applied to the simulation of wind flows and rainfall in mountain and urban area. Several GIS and CAD data were used for the preparation of shape model and an automatic mesh generation method based on Delaunay method was developed. The present method is shown to be a useful planning and design tool for the natural disasters and the change of environments.
