Choosing 2D vs. 3D, setting simulation time, and defining boundary conditions (e.g., for absorption or for arrays). 3. Sources & Monitors
In a passive device, this violates energy conservation. It happens if your source injects power inside a PML layer, or if the simulation terminates before the fields fully pass through the monitor.
