Continuing the discussion from Multimode source as an input:
Is it possible to calculate mode profiles (e.g. for aforementioned 50 modes) in MODE Solutions, save them and later use as input source in FDTD Solutions?
I have already found a solution to the additional question - FDE Data Export.
I managed to export mode profiles from FDE in MODE Solutions (both to .mat and .ldf). Now I tried to import them as a new source (Sources -> Import ->Edit object -> Import Source). There is no option to load .ldf file and even when I chose it, nothing happened - instead there is possibility to load .fld files. When I tried to load .mat file with modes, I got error as below:
So, the question is still open - how can I import to FDTD Solutions the mode profiles I have obtained with MODE Solutions?
