Not all of the mass of a non-decaying 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). that enters the pathway necessarily has to exit the pathway. This is because when creating the fracture network A complex network of one-dimensional conduits used by a Network Pathway to describe contaminant transport through fractured rock systems., not all of the locations where flow is discharged from the system need to be identified as sinks. Mass that exits the system elsewhere is effectively "lost" and will never re-enter other GoldSim pathways. Note, however, that when GoldSim reports the total mass in the pathway, it includes this "lost" mass.
If you do not wish to "lose" any mass in a 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., all discharge locations for the fracture network must be specifically mapped sinks.
