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。
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.
