Abstract:

A numerical simulation code for subsurface transport processes. It models 3D, time-dependent, multiphase, multicomponent, non-isothermal, reactive flow through porous and fractured media. Capabilities: flow of gas, water, oil and heat: flow of air, water, and heat; multiple chemically reactive and sorbing tracers; finite element/finite volume formulation; coupled stress module; saturated and unsaturated media; double porosity and double porosity/double permeability capabilities.
