ANSYS中AZ,VOLT自由度的SOLID117单元三相电流加载

有谁知道SOLID117单元AZ,VOLT自由度用F，N，AMPS，这个命令怎么加三相电流吗？跪求！
源程序如下：

/PREP7
RN0=0.53/2-0.016 !导体内半径
RW0=0.53/2!导体外半径
RN1=0.98/2-0.016 !外壳内半径
RW1=0.98/2!外壳外半径
HX=0.25
LEN=6
L1=1.47
L2=3.92   !空气层外半径
LX=0.24
I=14000   !电流幅值

自问自答？ 你不是加了吗？

谢谢楼上的回帖！我是加了，只是不确定对不对。:dizzy:

运行之后 查看电流密度幅值 相位好像没问题但是方向不是绕着线圈，而线圈磁导率确是绕着线圈。你说是不是加载前应该用局部极坐标系后面把那些点都耦合电压是什么原因啊？

谢谢楼上回复！局部坐标系似乎没有什么必要，耦合电压是因为假设电压相同，这个问题中分析的不是线圈的，是载流导体。我想了想这么加电流可以，所以程序应该是对的。PS：电流密度、幅值、相位分别怎么查看啊？:lol
