超限插值法在有限元网格划分中的应用

有限元网格划分是进行有限元数值模拟分析至关重要的一步。针对一些简单的裁剪曲面,如简单的四边曲边形,它的边界常常是十分复杂的.本文借助ACIS平台和超限插值对这些简单的裁剪曲面进行网格划分,使最终生成的网格质量得到了明显的改善。

Finite element mesh is a crucial step of numerical simulation. For some cutting surfaces, such as simple shape with curved edges, whose boundaries are often very complex. In this paper, using ACIS platform and transfinite interpolation,generate mesh on the cutting surfaces, the quality of the generated mesh significantly improved.
