The development of a mesh generation program using contour line data

등고선 데이터를 이용한 산악지형 유동해석 격자생성 프로그램 개발 및 그 응용

In the present study a mesh generation program has been developed by using DXF file. The program consists of DXF file reading and mapping algorithm, which projects the 2-D mesh point onto the triangular surface constructed by nearest three points. The present program has been tested for mesh generations for the road tunnel ventilation analysis and analysis of lava movement in mountain area.
