在有限元当中网格(包括影射网格和自由网格)划分对于计算结果的影响至关重要。提出一种多功能映射网格划分方法,该方法以平面的网格划分为基础,曲面和某些特殊实体的网格可以通过其投影面或基准面的网格划分数据自动生成。算例表明,该方法结构简单,适用范围广,通过合理规划可以得到质量良好的网格。
The mapped mesh is very important to the result in the finite element. A multifunctional mapped mesh method based on planar mesh is presented in this paper, the mesh of surface and some special solid can generate automatically from mesh data of its projection or datum plane. The example shows that this method has a property of simple structure, extensive applicability,and can obtain inerratic shape by proper arrangement.
