Does the FDTD simulation time depend directly on how close you can place the PML walls to the enclosed objects?
Hello @emh711 ,
In general, there isn't a connection between the simulation time and the distance between the PML boundaries and the simulation time. This post has more information on how to set the simulation time and the span of the simulation region: Key FDTD simulation settings
