工程船船体湿表面网格NAPA软件自动生成技术

利用NAPA软件中二次开发工具宏语言,通过引入模糊数学中的钟型隶属度函数和二次函数,开发出对平浮和带纵倾状态的船体湿表面网格自动划分模块。该模块不但可以快速和准确地划分船体网格,还可以生成直接被HydroStar软件调用的输入文件,并且通过控制输出文件的格式可以生成符合其他水动力软件调用的船体湿表面网格格式。

Automatic Grid Generation by NAPA for the Hull Wetted Surface of a Workboat

By using the macro-language,which is the secondary development tool in NAPA,the bell function and quadratic function in fuzzy mathematics are introduced into the automatic grid distribution module for wetted surface of ships on even keel or in trim.This module can not only plot the grid rapidly and exactly,but also generate the input file that can be called directly by HydroStar,as well as control the output format so as to generate various hull wetted surface grid formats that can be called by other hydrodynamic software.
