OpenBTE solves transport at the nondiffusive level. Current focus is phonon transport.

Developed by Giuseppe Romano (romanog@mit.edu).

Coming soon: Steady-state BTE using the full scattering operator Link. You can provide your own scattering operator (only upper diagonal) and perform space-dependent simulations.
