Hi!
I'm a new one for meep.
I'm now doing a simulation about a simple reflection from air to water.
But there's an error here:
meep: incorrect dataset size (30752000 vs. 0) in load_dft_hdf5
./trial6-refl-flux.h5:ex_dft
I've searched the same problem on net, it says to make the grid and flux
region
But I don't know how to change. Could anyone help me a little? Thanks a lot!
