This section of the Help files discusses the basic building blocks of an environmental simulation: 1) the species which are to be simulated; and 2) the environmental media in which these species are transported and stored.
Within GoldSim, these are collectively referred to as materials. GoldSim provides three specialized material elements: Species, Fluid and Solid. Specification of these material elements is the first step in representing an environmental system within GoldSim.
