摘要
基于开孔实体的参数化特征模型思想,本文提出了一种非自由边界分割有限元网格划分方法,可以针对开孔实体的几何特征和力学特征,对多种类型的开孔构件进行全六面体网格划分,生成的网格质量均匀、局部加密方便且疏密过渡合理。经实例应用表明,此种网格划分方法具有通用性强、简单、实用、高效等特点。
One method is studied in this paper, which aims at the geometrical characteristic of cylinder with holes and can operate mesh generation on multi-kind cylinder with holes. The efficiency and precision of this method is proved by examples, which is valuable for practical applications.
