There has been interesting research on the superconducting diode recently. A possible structure for this is the Superconductor/Ferroelectric/Superconductor (S/FE/S) Josephson junction. Our goal is to simulate a S/FE/S junction with a magnetic field and see if this leads to a superconducting diode effect. First this junction and its properties are studied through a numerical simulation. Then a magnetic field is applied and we look at how this affects the junction. For our simulation we use the Velocity Verlet method. We start by simulating a normal RCSJ. The results agree with what we expect from the theory, however there is small but noticeable error which we attribute to the numerical method. Next a S/FE/S junction is simulated. The polarisation of the ferroelectric only affects the RCSJ when it oscillates at a frequency which is close to the plasma frequency. If we apply a magnetic field we see small gaps for the retrapping current however these are close to the numerical error thus they are to small too be detected by our simulation.
