Hello,

I am currently working on a 3-D, time-dependent model that uses the magnetic fields interface. This model uses the Coil feature to excite a 3-D conductive structure with a specified voltage waveform. This part of the model works as expected.

I am now trying to add some additional functionality which allows part of the "coil" to move with respect to the rest of the conductive structure. I have implemented the moving mesh feature as well as some global ODEs to describe the movement. In addition, I've switched the geometry to an assembly and defined an identity boundary pair between the moving and stationary structures. I then defined a continuity boundary condition within the magnetic fields interface for this identity pair.

Now, the coil functionality is not working as before. Even with the moving mesh and ODEs removed, the coil feature appears to not function properly using an assembly with identity pairs. The model will solve, but no current flows through the "moving" portion of the coil.

Is there something simple I have missed somewhere that will allow the coil feature to function properly with an assembly? Alternatively, is there a better way to excite my "coil" aside from the coil feature? Unfortunately, I am unable to upload my .mph file due to some sensitive information within, but I would appreciate any advice you can offer.

Thanks!
