Network Pathway Outputs

Network pathways have at least two outputs:

• Mass_in_Pathway. This is a vector A one-dimensional array. by species The chemical (or non-chemical, such as bacterial or viral) constituents that are stored and transported through an environmental system in a contaminant transport model. In GoldSim, the Species element defines all of the contaminant species being simulated (and their properties). with dimensions An output attribute for an element that defines the dimensionality (in terms of Length, Time and other fundamental dimensions) of the output. of mass. It represents the total mass of each species in the Network pathway A transport pathway element that provides a computationally efficient way to simulate large, complex networks of one-dimensional conduits in order to describe contaminant transport through fractured rock systems..
• 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 A special type of Fluid element that provides a basis for defining partition coefficients between media for the various species in the model (i.e., the ratio of the species’ concentration in the medium to its concentration in the Reference Fluid at equilibrium). 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 A mass flux link in which a quantity of a medium is specified to flow from one pathway to another, carrying dissolved, sorbed, and/or suspended species with it. 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 A discrete interval of time used in dynamic simulations.. 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.
