NURBS曲面的有限元网格三角剖分

FINITE ELEMENT MESH GENERATION OF NURBS SURFACE

摘要: 主要介绍一种NURBS曲面的有限元网格三角剖分算法。首先讨论NURBS曲面的离散算法,接着在此基础上,提出了利用网格前沿技术剖分NURBS曲面的算法,并且网格单元和结点同时生成。

Abstract: A general algorithm for generating finite element mesh of NURBS surface is presented in this paper.First,algorithm for tessellating a NURBS surface is discussed.Then,advancing front technique of NURBS surface is proposed.Using this algorithm,elements and nodes can be generated at the same phase.
