摘要
研究了三维表面有限元网格自动生成的技术,利用映射法实现了模型表面的三角网格剖分。基于STEP文件格式的模型的导入和重建,将模型的每个表面映射至参数空间,利用推进波前法生成参数面网格,然后映射回三维表面。研制了一套网格剖分策略,运用该策略对多种类型表面进行了分析求解。
The technologies of automatic mesh generation for 3D surface finite element meshes are discussed. Triangulation of surface is implemented by adopting mapping approach, The geometry and topology information of every surface is mapped and extracted to 2D parametric space when model is imported and reconstructed according to the data from STEP files. The meshes are generated on the parametric plane by the advancing front approach. Then the meshes are mapped to the 3D surface.
