Hi Areej,

The first step in any divergence issue is to identify if it is due to the PML boundaries or if it is a stability issue. I will recommend you to visit this page: Troubleshooting diverging simulations in FDTD. You can change all the PML boundaries to Metal boundaries and let me know if the simulation converges or not.
