Summary of Limitations on the Use of Network Pathways

While Network pathways are versatile and powerful, they have the same limitations as Pipe pathways, which are worth summarizing here:

• Unlike Cell and Aquifer pathways, GoldSim does not apply solubility limits within Network pathways.
• If the properties of a fracture set (e.g., partition coefficients The ratio of the species’ concentration in a medium to its concentration in the Reference Fluid at equilibrium. Partition coefficients are inputs to Solid and Fluid elements.) change as a function of time, GoldSim has to use an approximation. The approximation is that 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). are discharged from a pathway based on the properties of the pathway at the time the species (or their parents) entered it.
• "Looping" reaction chains (A decays to B and B decays to A) are not permitted. Defining such reaction loops in a model that uses 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. will result in a fatal error message.

In addition, it is also important to note that when you clone a Network pathway, two properties are not cloned: 1) the fracture network A complex network of one-dimensional conduits used by a Network Pathway to describe contaminant transport through fractured rock systems.; and 2) the number of watch groups (so that if you edit one of the clones Sets of elements whose properties change simultaneously when any one member of the set is edited., the changes are not reflected in the other clones).
