摘要
本文介绍的三维湿表面网格的自动生成算法，不但可完成型值表各站型线的等弧长插值拟合，而且能够在沿船长方向的任意位置上进行站的加密和插值，从而自动生成三维湿表面网格。该算法的实现依赖于一套完整的图、形用户界面。此界面用Ｕｎｉｘ平台的Ｍｏｔｉｆ、Ｃ和ＧＬ编制，友好灵活，方便易用。
In the 3D Hydro--Elastic analysis, it is required to divide the wet surface of a ship into grids. This paper introduces a 3D grid auto-generating algorithm of ship wet surface, which can finish the equal arcs interpolation of every station of the ship body plan, and can also complete the station interpolation and sophistication at any arbitrary position along the ship length direction. The realization of this algorithm depends on a set of GUI interface. Based on the UNIX platform, the interface is programmed by Motif, ANSI C and GL. It is friendly, flexible and easy to use.
