The Boundary Conditions Card for STOMP-CO2e can be used to specify boundary conditions for the energy, fluid flow, or salt. Boundary conditions are one of two types: 1) Dirichlet or 2) Neumann. Dirichlet-type boundary conditions specify state conditions at the boundary surface centroid (i.e., temperature, pressure, phase saturation). Neumann-type boundary conditions specify either fluxes (i.e., heat flux, fluid flux, salt flux) across a boundary surface. For STOMP-CO2E the specification order is always: 1) energy, 2) aqueous, 3) gas, 4) dissolved salt, and 5) reactive species.
