基于面元模型的FDTD网格及涂敷层网格生成技术

The FDTD Mesh Generation Technique Based on Facet Models and the Coating Grids Generation

提出了一种基于面元模型的FDTD网格剖分技术和涂敷层网格的生成技术。这种网格剖分技术可以方便地剖分封闭的面元模型和实体模型。针对均匀涂敷复杂模型难以直接产生的问题,提出在FDTD网格模型基础上,生成涂敷网格模型的方法。这种方法很容易得到任意复杂FDTD网格模型的涂敷层网格模型,克服了复杂表面模型和实体模型直接产生涂敷模型的困难。

A new FDTD mesh generation technique based on facet models and a new technique of generating coating grids are proposed.The closed facet models and the entity models can be meshed using the meshing technique.In view of complexity and difficulty for coated models generation directly,it is proposed that the coating grids can be generated based on the FDTD grid models.The method is very easy to obtain the coating grid models of the complex FDTD grid models.
