Preprocess of 2-dimensional domain mesh generation─disintegration of the domain
Zhan Qionghua · Dianji yu kongzhi xuebao · 2000
A method to disintegrate arbitrary 2- dimensional domain into connected subdomains has been presented. Boundary data was first recombined into polyline--groups and being checked, then oriented loops were formed from the polyline--groups. Finally the oriented loops were disintegrated and transformed into edges of subdomains. The method is robust, needs simple data of the meshing domain, which can be used as preprocess part of Finite Element Analyzer(FEA) or other mesh generators.
