These are the steps for my capacitor simulation
1. set two solid blocks (dimensions (25x1x20) ) 1 distance away from each other.
2. set a solid box (65x43x60) to surround the plates of the capacitor.
3. subtracted plates from the surrounding box.
4. set the plates to be copper and surrounding box to be air.
5. set one plate to be port 1 ( defined as input) ; set the other plate to be port 2; used energy method
6. set the surrounding box to be ground
7.meshed and got the solution
I calculated theoretically what the capacitance for a parallel plate capacitor should be 0.004425 pF
My COMSOL result is 30% off ( 0.005736977 pF). I do not believe this is realistic.
Can somebody help me find an error in my process?
