摘要
针对水利水电大型工程结构复杂有限元建模难,采用AutoLISP语言开发了辅助复杂有限元网格构造的一系列工具,包括基本图形的便捷操作、网格的快速构造及输出接口。通过界面定制方法使扩充命令方便地从工具栏调用,并制作了相应的安装程序使该网格工具能顺利地融入AutoCAD原功能中。实例应用结果表明,该工具行之有效,可供类似工程建模借鉴。
Some tools are implemented with AutoLISP language to build complex FEM meshes,including basic graph operations, rapidly mesh building methods, and output interfaces. All extended commands have twenty numbers, such as moving point of intersection, breaking lines each other, copying and linking lines to form meshes, etc. With interface user defined,these commands can be used easily by toolbar method. The according setup program is also supplied to combine mesh tools with AutoCAD known functions. All functions are tested successfully in AutoCAD 2004 Chinese version.
