I am not sure what it means and what I have to do to resolve it. The external terminal borders the edge of the vacuum box in which I have put the design. Do I need to assign boundary conditions to the faces on which the coil terminals are ending? The current enters the coils on the left and exits on the right. The coils have the assigned coil terminal excitations and have been added to a winding, and the current direction is correct in both. Any insight would be greatly appreciated&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2025\/01\/15-01-2025-1736938061-mceclip0.png\" \/> <img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2025\/01\/15-01-2025-1736938324-mceclip1.png\" \/>&lt;\/p&gt;&lt;p&gt;*Global &#8211; Messages&lt;br&gt;&nbsp; &nbsp; [error] Illegal external terminal &#8216;Current_In&#8217;: An external terminal must border the edge of the problem region and coincides with the surface of a 3D object.
