+ Dusty Gas transport model.
+
+ The Dusty Gas model is a mulicomponent 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.
