In brief, my model consists of a rat head (red box) that are placed between 2 copper plates (blue arrows). I want to study the E-fields in the rat head when applying 42V at 200kHz.
Initially, I tried to use lumped port as an excitation in my control model, but the results showed that the locations of the port affected the E-fields You can find the results in this post - https://forum.ansys.com/discussion/31898/e-field-in-insulator#latest.
This problem occurred when using voltage source as well. To prevent the port or sheet cutting through or even touch the rat head, I created ÔÇ£extended wires" and connected them at the end (as shown below). This seems to give reasonable results for my study.
Regardless of using lumped port or voltage, what I try to do is to maintain the voltage difference between 2 copper plates at 42V and prevent unwanted effects of the port's placement on E-fields.
My questions are:
If this is an incorrect way to use voltage source, can you please let me know how this excitation should be done?
Would you kindly explain why you recommend a circuit port, instead of voltage source? And what is a circuit port that you prefer to? Do you mean wave port or lumped port?
I only know the applied voltage (42V) for my study. I don't know how much power or current it requires. If possible, I'm interested to learn how much power or current the copper plates consume.
