Musubi is a parallel multi-level lattice Boltzmann solver that allows for the simulation of multiple species with the Maxwell-Stefan model. Its main application domain are incompressible flows.

Its public source code repository is hosted on OSDN. Please see the documentation for its usage and more details.
