Boundary Conditions

Boundary conditions, i.e., what occurs at boundaries of the transport domain, need to be specified for each process that is simulated. For boundary conditions for particular processes, see the Water Flow Boundary Conditions, Solute Transport Boundary Conditions, and Heat Transport Boundary Conditions Topics.

Using command Edit Water Flow Boundary Conditions, users can specify boundary conditions for water flow. Specification of the boundary conditions is relatively straightforward. Users must first select from the Navigator Bar the particular Boundary Conditions (i.e., water flow, solute transport, or heat transport) and then click on the Edit Bar on the particular boundary condition (e.g., constant head). They subsequently need to move the mouse to the selected position and click the left mouse button. Implementation of the boundary condition terminates with a repeated click of the left mouse button. The boundary nodes will acquire the same color as the corresponding type of the boundary condition.
