[Meep-discuss] dispersive material and n less than one?

I've been working on simulating a non-ideal metal, and it seems to run well with my calculated polarizations if I choose n>=1. However, there seems to be a limit on how low I can make n. At my wavelength of interest, Ag has n=0.226, and I can't go below about n=0.6 without the simulation "blowin

[Meep-discuss] "Crazy weird splitting error" from meep-mpi

I'm trying to run a simulation of a waveguide in the 3D "woodpile" lattice. The .ctl file (copied below) sets up the geometry for one axial period using Bloch boundary conditions. Just calling (init-fields) results in the error: num[0] = 1 num[0] = 1 num[1] = 1 num[2] = 1 meep: Crazy weird spl
