Hello,
I tried to modle a meshed coil. I defined two cylinders and made a subtraction. Then I made a cut object. Now I have a face for the enternal and exiting face (one of the orange faces).
Then I made a coil conductor Region.
After that I wanted to 'orient wired of coil conductor regons'. I want Internal terminals. So I selected one of the two faces from the 'cut object'- Operation. After that I checked the physics:

I don't know what is wrong. What can I do to solve the Problem?
Thank you in advance.
