基于任意六面体单元数据场的剖面可视化算法

Visualization of section for three-dimensional FEM analysis with hexahedral elements

三维有限元计算结果的可视化是分析有限元计算结果的重要手段 ,针对八节点六面体单元 ,结合三角形网格等值线算法 ,提出了基于该单元类型任意剖面等值线及彩色云图的生成方法 ,并通过实例说明 ,该算法不仅可以快速地生成空间实体任意剖面上的等值线和云图 ,而且还可以细化剖面上数据 。

Visualization is an important method for anal yzing three-dimensional F EM data. based on algorithm of contour line for triangle-mesh, a general method of arbitrary section visualization for 3D 8-node hexahedral elem e nts is presented. The samples have proved that the method for creating contour l ine and color contour image on section of 3D part is feasible and reliable, mean while it provide fined mesh and display the distribution of three-dimensional f ield in internal of part effectively.
