HGC can simulate density-dependent flow processes in integrated unsaturated and saturated groundwater zones.
Reactive chemical transport module:
HGC can simulate mixed fast equilibrium and slow kinetic reactions simultaneously. Reactions include aqueous complexation, multi-site adsorption/desorption, multi-site ion-exchange, precipitation/dissolution, oxidation/reduction, acid-base reactions, microbial-mediated reactions, etc. HGC also offers linear KD, Freundlich, Langmuir models.
Thermal transport module:
Temperature changes are induced by fluid injection and chemical reactions.
Linear geo-mechanics module:
Rock deformation and fault displacement are affected by fluid pressure, thermal pressure, and chemical concentrations.
