Hi all,
My project involves building a coil which consists of a current source going through the inner conductor and closing the loop by going through the outer conductor.
-There seems to be an error trying to specify the direction of the current in the multi-turn coil node. While I was selecting the edges, the directions didn't go the way I intended them to, which is counter clockwise starting from/ending at [current source]
-Also, if I wanted to have a current source with 1 Amps with a 128MHz frequency, would the study be frequency instead of stationary?
Attached is the file.
Thanks!

Hi Jeff,
The Multi-Turn Coil -> Circular type is only supported for a circular conductors, for example, toroid (en.wikipedia.org/wiki/Toroid) or Circular. However, in your case this is not true. For this type of configurations, you must use the Multi-Turn Coil -> Numeric. See this example for detail of numeric type Multi-Turn Coil settings.

-Also, if I wanted to have a current source with 1 Amps with a 128MHz frequency, would the study be frequency instead of stationary?
->> Yes, you could do this using the Frequency Domain study with 128[MHz] frequency.

Hi Nirmal,
Thank you very much for the response. I have looked over the tutorials for the numeric multi-turn coil and hopefully made the proper changes.
When I tried to compute, I kept on getting a "COMSOL assertion failure" for stationary solver 2. Do you have any idea why that is?
Best,
Jeff
