IntroductionThe Context
I in a deep geological Nuclear Waste Repository there could behydrogen gas generation due to corrosion of the steelengineered barriers
I the flow could be saturated (' only the liquid phase) insome regionsand unsaturated (a ”liquid + gas” mixture) in other ones
I Problem in simulations, using standard models, when there isa phase appearance/disappearance
– - variable switching or variable substitution– - small artificial non-zero saturation
