Reply To: Is it possible to apply a current to a moving conductor?

Dear thank you so much for your help. The inner band does the trick.
However, when I try to use a ring shaped inner band I get an error massage.
A ring shaped inner band and outer band would be necessary for my problem, because of the ring shaped vacuum vessel containing the conductor. Is this possible in Maxwell?
I thought of using a slice of the ring shaped geometry, but it produces the same error massage.
When the inner band is a non-model object I don't get this error, but the current in the conductor is zero again.
Master/Slave boundaries generate an error, that these boundaries cannot touch the band. This error persists even when the boundaries are well inside the band.
Thank you very much for your help.
