| Abstract: | In light of the discrete problem of 3_D finite element analysis for complex structures, an assembled_dissecting technology to solve the problem of complex structure's dissection is put forward.Based on it,firstly, a structure is divided into several regular parts and several irregular parts;secondly,regular parts' automatic dissecting is realized by using program;irregular parts' semi_automatic dissecting is realized by using AutoCAD and some graphics interface program;at last,all parts' meshes are assembled into integrity meshes of a structure. In the meantime,typical algorithms of problems related and an example are given also. |
