Hi guys.
I am trying to model a structure, which has a capacitor build into it with SiO2 and air as dielectric. For this I started to model a 2D structure and plotted the electric field as "electric potential -> surface". This can be seen in the attached file "Simple_forsoeg_med_grid". In this plot the dieelectric, i.e. the air and silicin dioxide is affected by the electric field.
However, in my 3D model, "3d_square_corners_with_extrude", where I've also plotted an "electric potential -> surface", it's only the copper layer that deviates from the rest of the model, in terms of electric field. I do have air around the structure in both cases.
I've attached screenshots two screenshots to show what I mean.
Hope you can point me in the direction of an answer to this issue.
