This talk will review structural properties of the equations used to
model porous flows involving multiple components undergoing phase
transitions. These equations only model the gross properties of these
problems since a precise description of the physical system is neither
available nor computationally tractable. The saddle point structure
resulting from the interaction between dissipation and free energy (or
entropy) of the fluids will be highlighted. The construction of
numerical schemes which are robust in the presence of degeneracy, and
solution techniques which exploit the saddle point structure, will be
