Hi,

I am getting the below error message. 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

Hi, 

This error points to the aligment between the in/out current terminals and the Region surface. If you have created the Region drawing a box, is possible that you have a small gap (not easy to see). My advise is to create the Region going to Draw/Region, then select the "Pad individual directions" and ensure that in the Y direction (positive and negative) the percentage is zero.

If you still have an error, please ensure that all the wires are long enough to touch the Region.

I hope it helps

Hi Ivonne, thanks for the swift reply.

I drew the copper wire very long then used the split command and selected split by face and chose the appropriate face on the Region box so that the wire is the exact length to interest with the Region box. I am still getting the same error message. Do I need to assign boundary conditions to the faces of the Region Box where the copper coil interacts for current in and current out?
