Solvers submodule includes a generic solver in case you already have a sparse matrix solver, or in case you have no solver at all. Example file now uses alternate solvers if available, and has a nicer way of picking which solver gets used.
fdfd_tools
fdfd_tools is a python package containing utilities for creating and analyzing 2D and 3D finite-difference frequency-domain (FDFD) electromagnetic simulations.
Contents
- Library of sparse matrices for representing the electromagnetic wave equation in 3D, as well as auxiliary matrices for conversion between fields
- Waveguide mode solver and waveguide mode operators
- Stretched-coordinate PML boundaries (SCPML)
- Functional versions of most operators
- Anisotropic media (eps_xx, eps_yy, eps_zz, mu_xx, ...)
This package does not provide a matrix solver. The waveguide mode solver uses scipy's eigenvalue solver; I recommend a GPU-based iterative solver (eg. those included in MAGMA). You will need the ability to solve complex symmetric (non-Hermitian) linear systems, ideally with double precision.
