The
most versatile pathway element is the Cell pathway. Cell pathways would typically be applied to
simulate discrete, well-mixed environmental compartments such as ponds, lakes,
shallow soil compartments, or the atmosphere. In some cases, a series of
Cells may also be the best way to simulate features such as aquifers and
rivers.
The editing dialog for a Cell pathway looks like this:
The primary input that must be defined for a Cell pathway is the quantity of each medium that is present in the pathway. The Reference Fluid is automatically present in each new Cell. Media are added and deleted using the Add Medium and Delete Medium buttons. The number of separate media present in a pathway is unlimited, but most Cell pathways will typically include no more than two or three.
The output of a Cell pathway element includes the total mass of each species in the pathway, and the concentration of each species in each medium in the pathway.
