FDTD Simulation

[abuammarazmi]

Hello,
I want to do a FDTD simulation of my 2d photonic crystal structure in AETHER. I wanted to know if there are limitations of the computational size ? My simulation window is like 16*16 microns. I have attached photo for a reference.

Hello,

There's no hardcoded limit, so the limit is going to be your computer.
With that said, looking at the code there might be a intrinsic limit of around 1 billion points in a grid.

If you're trying to do a 2D calculation you should be fine.
With that said, do remember that the field travels along z. In your screenshot you've set the z depth to 0.

Thank you so much for the clarification!
