直线感应电机切半symmetry FEM Coil Current Path 问题

JMAG 跑完Mesh, Run active case 报错如下

A current path was not found.
Check whether or not the following are so, and correct the analysis model if necessary.

(1) The current inflow faces are set correctly.
(2) The energization regions are not divided.
Set coils that are connected to one another across a periodic boundary face as one energization region. If each such coil is set as an energization region individually, no current will flow through such coils.
(3) For a coil in which there is inflow current through a symmetric boundary face and outflow current through a different symmetric boundary face, an inflow face is set on the inflow current symmetric boundary face. And a symmetric boundary condition is set on the outflow face.
(4) For a coil in which there is inflow current through a periodic boundary face and outflow current through a different periodic boundary face, an inflow face is set on the inflow current periodic boundary face.
(5) Unnecessary boundary conditions are not set in the energization regions.
(6) When is , a coil inflow region section can be created on a vertical plane containing an energization direction start point.
If an energizing direction start point is not in an energization region or is set near a coil corner, a coil inflow region section may not be able to be defined. In such a case, move the start point.
(7) There are no duplicate elements.
Check all elements in the nei**orhood of the element with element ID 55330.



线圈从中间切了 1/2 里面电流 方向 不管用vector 还是 inflow face 都出错。如下图可以理解,求教解决办法!

救救**吧,我为了节约Run Analysis时间,把原本完整的直线感应电机沿中线X轴方向(因为我是X轴两边对称建模的)切半。 我设置好了condition,把线圈上进和上出的线圈分开,并且inflow faces 和 flowout faces 分开,并且symmetry condition 把 这两个faces 集合 分开设置。 但是无论我如何根据报错去改,都还是报错如下图。 希望高手能帮我解决这个难题,拜托了!

拜托了!
