Hi there,
There might be several similar threads, but - please believe me - I couldn't find what I am searching for.
I am in a project where we use HFSS for some simulations. Since we got really screwed up results for shielded cable models (compared to none shielded ones) I was trying to just simulate the capacitance value of our cable geometry (and hopefully getting similar results than the calculated ones of the cross section values (7.9mm diameter of conductor, 10.1mm conductor + insulation, 11mm conductor + insulation + shield led to something around 370 pF/m)
So my main goal is to confirm that value by using the 3D model.
So I set up a simple model of that cable with only cylinders (open ends) of 1m length (to be exact I used CreateLine and CreatePolyline) and a radiation boundary which is a cylinder of 2m length and 1m diameter.
By that point I got stuck. How to calculate the capacitance of that cable? I didn't find a way using a voltage port (which we are using in our project) nor with a lumped port.
Thanks in advance for your help and a happy new year!
