Surface Flux Card (CO2E)

STOMP-CO2e solves coupled conservation equations for energy, water mass, CO₂ mass and salt mass in variably saturated geologic media under nonisothermal conditions.  The simulator additional solves equations for the transport of passive solutes, allowing for partitioning of the solutes between the host rock/soil, aqueous phase, and gas phase. When the ECKEChem module is implemented with the simulator, the simulator has capabilities for solving reactive transport problems involving equilibrium, kinetic, and conservation type geochemical equations.  The Surface Flux Card allows the user to specify the output of rates and integrals of fluxes crossing grid-cell surfaces.  For this operational mode the fluxes of interest are those associate with advection of the aqueous and gas phase, and heat transport. If the simulation involves passive solutes, the Surface Flux Card is used to specify the output of transport rates and integrals of solutes crossing grid-cell surfaces.  Likewise if the simulation involves reactive species and code implementation includes the ECKEChem module, then the the Surface Flux Card is used to specify the output of transport rates and integrals of solutes crossing grid-cell surfaces.
