摘要
针对有限元分析数据场的特点，提出了一种四面体剖分方法，并采用了一种快速搜索的数据结构，显著地减少了计算时间，有效地实现了有限元后处理程序中的等值面生成．实例表明，该方法适用于数据场稀疏、不规则并且具有多种体单元的有限元模型。
According to the feature of FEM data fields,
an effective method of isosurface generation is presented utilizing the subdivided tetrahedron and
the data structure for the fast searching. The example demonstrates that the method is not only
especially appropriate for the FEM models having sparse, irregular data fields and multiform body
element, but also effectively guarantees the topological consistency and correctness of
isosurface.
