"""
Dusty Gas transport model.
The Dusty Gas model is a multicomponent transport model for gas
transport through the pores of a stationary porous medium. This
example shows how to create a transport manager that implements the
Dusty Gas model and use it to compute the multicomponent diffusion
coefficients.
