iam trying to simulate a directional coupler via varFDTD
and i’ve got the problem that my field profile is always cut off after a specific propagation distance,
no matter what parameters i choose (geometry of structure, mesh, boundary conditions, etc.)
the simulation is running fine until the end, i dont receive any errors.
anybody encountered a similar problem? is it maybe due low memory?
iam running the simulations on a quad-core cpu, 8GB RAM.
thanks for all your help!
