Hi, everybody. There is a problem always confusing me.
Sometimes when I run the 3D FDTD simulation, the autoshutoff level will increase (maybe to about 5) and then decrease to 1e-5.
Is this a problem for simulation?
Hello @liu ,
No, this shouldn't be a problem. The autoshutoff level is just an estimate of the remaining energy in the simulation region so it's normal for the autoshutoff level to increase a bit over the course of the simulation. I would say going up to 5 is a bit unusual but it's not necessarily a problem. Still, you might want to double check some of the issues that can cause a diverging simulation on this page, to make sure there is no divergence in the simulation:
