- Even if a 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). or Media Materials (such as water, sand, clay, air) that constitute (are contained within) transport pathways. GoldSim provides two types of elements for defining media: Fluids and Solids. (Fluid or Solid) element is in an inactive Container, these elements are never deactivated. If one of these elements is inside an inactive Container, the element will ignore this fact.
- Species elements and Pathway elements can exist within a conditional Container, but you cannot deactivate the Container. That is, these elements can start in Containers that are initially inactive, but cannot exist in Containers that start active, and subsequently deactivate. Trying to deactivate a Container with a Pathway or a Species element will result in a Fatal Error.
- Source elements cannot be activated or deactivated during a simulation. If a Source is located within a conditional Container, the Container must be set to inactive or active at the beginning of the simulation and its status cannot change during the simulation.
- If an active Pathway is linked (via an outflow) to a Pathway that is initially inactive, a Fatal Error will be displayed
- If a Pathway is initially inactive, no decay calculations are carried out within the Pathway until it is activated.
In addition, although GoldSim does not specifically prevent it, Cells in the same cell net A network of interconnected Cell pathways that are directly linked by coupled mass flux links. should never be spread between active and inactive Containers, as this is likely to lead to unrealistic behavior and results.
