I want to learn about E-field across the geometry. Can the directed line be perpendicular to the face (in y direction) that I will apply the voltage on? if not, how should I assign this line? It seems like the directed line can only go along the x- and z-direction.

Thank you.

The setting of my study is pretty similar to two parallel metal plates, but with 7 layers of different materials between 2 plates.

If you want to simulate a model similar to parallel plate capacitor then please use Q3D instead of HFSS.
It can be efficiently implemented in Q3D.
All the very best.

My operating conditions are 42V and 200kHz. I want to study electrodynamics, rather than electrostatics. For clarification, there are an air gap and other 7 layers of materials with high dielectric constants (e>100) between two parallel plates.
Is there a way to add a voltage on one plate and set GND to the other plate without defining the E-field direction first?
I tried lumped port, but different locations of the port give me different field strengths across the model.
Thank you.

Hello
Have you solved this problem? I am having exactly same problem with yours too.
Could you leave a comment if you figured out how to apply the E-field to parallel plates with voltage source excitation?
Thank you.

I created a "wire" for each plate and connected them at the end of the wires. It seems to give me reasonable results, so I have been using it this way.
However, I don't know if it is a correct way to implement voltage source excitation. I asked in this post, but got no response: /forum/discussion/32318/voltage-excitation-ansys-hfss#latest
