STOMP

Boundary Conditions Card (W)

This card is used to impose state conditions or fluxes across grid-cell surfaces that are not coupled to an adjacent grid cell (e.g., external boundary surfaces).  The Boundary Conditions Card is designed to allow the user to specify boundary conditions for the aqueous phase, passive solutes and reactive species. Depending on the nature of the boundary condition and problem, the boundary condition input structure may be quite simple to rather complex.  For STOMP-W the specification order is always: 1) aqueous, 2) passive solutes, and 3) reactive species.

  • General concepts for applying boundary conditions are provided on the Card Description page.

  • Options for the three classes of boundary conditions (i.e., aqueous, solutes, and species) are provided on the Card Options page.

  • Formatting instructions for specifying boundary conditions are provided on the Card Syntax page.

  • Examples of Boundary Conditions Cards with and without solutes and geochemistry are provided on the Card Examples page.
