TY - JOUR A1 - Kashiyama, Kazuo A1 - Hamada, Hidetaka A1 - Taniguchi, Takeo T1 - Large Scale Finite Element Simulation and Modeling Using GIS/CAD for Environmental Flows in Urban Area N2 - A large-scale computer modeling and simulation method is presented for environmental flows in 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. Parallel finite element method based on domain decomposition method was employed for the numerical simulation of natural phenomena. The present method was applied to the simulation of flood flow and wind flow in urban area. The present method is shown to be a useful planning and design tool for the natural disasters and the change of environments.

Following a theoretical model development, a series of simulation runs are tried. The model allocates people who commute to CBD from residential zones along a transportation corridor. As a result of many simulation analyses, it is shown that automobiles need much more traffic space in comparison with the transit as is shown by the proposed traffic space ratio both in CBD and along the corridor.

This system calculates outdoor surface temperatures in order to evaluate the thermal impact of a design factor in outdoor space. In this study, the previous heat balance simulation system was improved to predict the surface temperature of a proposed design using 3D-CAD. This system is able to input the complicated outdoor spatial forms efficiently and also to evaluate the surface temperature distribution from any viewpoint.

We found in the study that the electricity consumption per capita has a tendency that is higher in city center and lower in suburbs in Utsunomiya city. It is also noted that there is little difference among total consumption between city center and suburbs, despite the fact that the density of electric appliances tends to increase in a small size house of city center and the amount of automobile energy consumption from residence is lower in city center than in suburbs.
