Abaqus自带RSG插件应用实例展示

一款可以上手的实例，讲解整个RSG插件的强大地方，避免重复工作。

如上图所示，圆柱电芯建模和阵列所有尺寸都列出，其中R 圆柱半径、L 圆柱长度、Numx x方向阵列数、Numy y方向阵列数量、DistanceX x方向阵列距离，其它部分为创建材料，分析类型，接触类型，载荷工况，网格划分，提交作业。

另外，还附带DB和plugin文件，写上一个icon进行，p.py文件将三个文件输出pyc加密文件：

具体代码为：（其中py_compile为python自带模块，无需下载安装）

import py_compile

py_compile.compile('a_plugin.py')

py_compile.compile('aDB.py')

py_compile.compile('aModul.py')
