In this work, we are concerned with robust parallel simulations of multicomponent flows in complex ge- ometries by an extended lattice Boltzmann method. In Zudrop et al. (2014)  we presented a model for the incompressible Navier–Stokes and Maxwell–Stefan diffusion equations. Here, we prove that the implicit-to-explicit variable transformation of the model is well-posed under weak constraints on the di- mensionless Maxwell–Stefan diffusivities. Furthermore, we analyze various boundary conditions for the multicomponent lattice Boltzmann model. These results make the model robust and well suited for com- plex geometries, which allows us to study realistic, large-scale mass transport applications.
