Hi, I am working on a project to study 2D electrostatic field when we have an aircraft in a 100 kV/m ambient electric field. 

For this I am stuck how to get the electric field variations when the aircraft is put inside the plates having the required electric field. In this, I am not getting variations outside the aircraft instead I am getting it on the aircraft body. I am using low frequency simulation in CST studio. 

Can anyone please help me and suggest how to do it in simulation.
