External pathways have two types of outputs:
•User-defined output arguments; and
•Mass flux link Outflows.
The user-defined outputs are optional (none need be defined). Their type and dimension are determined by the user when they are created.
For every advective mass flux link in which the External pathway is the Outflow (upstream) pathway, an output is created on the External pathway:
•Medium_to_Path2, where Medium is the name of the flowing medium (which is always the Reference Fluid), and Path2 is the name of the linked (Inflow) pathway. This is a vector by species, and has dimensions of mass/time. It represents the mass flux of each species from the External pathway to the downstream pathway.
It is important to understand that the mass flux outputs from an External Pathway represent the mass rate over the previous timestep. This can have implications if you choose to integrate one of these outputs (using an Integrator).
