Network Pathway Outputs

Network pathways have at least two outputs:

• Mass_in_Pathway. This is a vector by species with dimensions of mass. It represents the total mass of each species in the Network pathway.

• Concentration. This is a vector by species with dimensions of mass per volume. It represents the average concentration of each species in the Reference Fluid at the point(s) that it exits the Network pathway (i.e., it is computed as the total mass outflux divided by the total Reference Fluid flow rate).

For every advective mass flux link in which the Network pathway is the Outflow (upstream) pathway, an output is created on the pathway:

• Medium_to_Path2, where Medium is the name of the flowing medium, 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 Network pathway to the downstream pathway.

It is important to understand that the mass flux outputs from a Network 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).

For every Watch Group defined for the pathway, an output is created on the pathway:

• WatchNN, where NN is the Watch Group number. This is a vector by species, and has dimensions of mass/time. It represents the mass flux of each species from the Watch Group.
