[error] Verify conduction path 'Path1': For any conduction path that has current excitation(s) specified, at least two external current excitations should be specified. 

    [error] Verify conduction path 'Path2': For any conduction path that has current excitation(s) specified, at least two external current excitations should be specified. 

Maxwell3D仿真，遇到这种错误，说的是导体路径有两条，应该指的是模型有问题，哪里没有连接上。

为了查找问题，找到了一种方法：

1.鼠标右击，找到“Assign Excitation”，然后“Conduction Paths”，最后“show Conduction Paths”

 2.就可以看到Path，有几条路径都会显示在这里。（我是修复好了，只显示了一条）
