I'm currently on a trial license trying to evaluate this product for my company.
I have here an assembly of 3 connectors. One end is given a terminal condition (with 2000 or 3000 amps), the other is given a ground condition. I have a convective cooling coefficient of 5 just for room conditions.
I used a material property of 38[MS/m] for the electrical conductivity of the aluminum. The IACS % I saw was 41%, and so I just converted it.
My problem is twofold. First off, we ran a real life test on this assembly, and the temperature correlation is not close. As you'll see if you solve it, there is virtually no heating of the parts (at least compared to our experimental results).
Secondly, I am having a problem applying AC power. From what I've read, to apply a 60 HZ AC frequency current, I need to either do a frequency domain analysis. In my model, you'll see I ran 4 different studies, just to try and see how they run. In the studies that do get somewhat run, the heating is bare minimum, but does not have any frequency aspects to it. However, on the frequency and transient/stationary studies, I get a uniform room temperature solution.
What am I doing wrong? Am I just not understanding how these models are supposed to be setup? Or am I misunderstanding how the 60HZ frequency is supposed to be applied?
If joule heating is not the answer, what is your suggestions on how to go about the problem?
Lastly, can you perform a time dependant solution using a 60 hz frequency?
