abaqus INP扫盲与提高：*MATRIX GENERATE,STIFFNESS的验证

可以通过 inp文件 可以直接定义一个job:


   通过改变source实现，输入input file的路径即可。

   不过报错了。报错的原因是我输入的一个集合名称不存在。实际上我定义了这个集合FIBRE-0，但是集合好像是 part 下的，而不是assembly下的，所以会出错。我推测是这样。事实上也是这样的——见我下一篇博客。

*MATRIX GENERATE,STIFFNESS的验证

1. 一个边长为10的立方体，直接划分为一个单元C3D8R的inp文件：

*Heading

      8,          10.,           0.,           0.

用*MATRIX GENERATE,STIFFNESS生成的刚度阵文件如下：
