Re: [Meep-discuss] Run-time problem opening hdf5 files with hdf5-1.8.14

This can happen if you are trying to call "load-flux" in scheme (or load_flux() in python), but the file you are trying to load just doesn't exist. Like if you ran the waveguide bend tutorial example without first running the normalization. Best, Derek On Mon, Jul 30, 2018 at 4:25 PM John

[Meep-discuss] When does meep *not* perform subpixel averaging?

I saw that for user-defined materials, meep does not perform subpixel averaging. (1) If I specify my material geometry via "epsilon_input_file", does meep perform subpixel averaging after input and before simulation? (2) Under what situations does subpixel averaging not occur? Thanks for helping

Re: [Meep-discuss] Transmittance Spectrum of a Waveguide Bend

Hello Abdel, A waveguide eigenmode propagating through a straight waveguide should have zero loss (assuming lossless dielectrics and no surface roughness) so the transmittance is 1 and reflectance 0. This is why normalizing simulations of other structures by the results for a straight waveguide
