一种铺设算法及其在MSC.Patran平台上的实现

A Paving Algorithm and Its Implementation on MSC.Patran Platform

为了在船舶横向结构上自动生成有限元网格,基于前人对非结构化网格算法的理论研究,并引入一些新的规则,提出了一种铺设算法,并给出了其在MSC.Patran平台上的实现方法.相比较原有算法,新算法更适用于在细带状的二维区域上自动生成有限元网格,并允许设置约束条件.在船体横向构件中的应用表明,该算法优于已有算法.

In order to automatically generate finite element （FE） meshes in the transverse structure of a ship, this paper presents a paving algorithm and its implementation method on the MSC. Patran platform according to the exis- ting unstructured mesh algorithms and by introducing some new rules. As compared with the existing algorithms, the proposed algorithm is more suitable for the automatic generation of FE meshes in the narrow two-dimension areas where some constraints are allowed to set. The application to the transverse structure of a ship indicates that the proposed algorithm is superior to the existing ones.
