Hello..

I am trying to model a Primary terminal of A Current Transformer. The terminal is to carry a current of 300 Amps. I am stuck with how to inject the current into the system, so that I get the potential drop as well as the Heating of the terminal. Can anyone please help me out. I am attaching my model here.

I have tried with potential at the terminal but still I am getting error. If anyone can help me , I would be grateful .

Thanks in advance.. :)

Hi, I am currently trying to model one of my inductors that I have done many times in past versions of COMSOL but appear to get the same error. I will be looking into this.

Just so you know, if you are still looking, the inductor_3d example model in the model library shows how it works somewhat well. I had to create a little air element between my terminals that acted as the terminal port with both + and - sides, and using the electrical circuit setup. That model is a good guide though.
