Viewing a Cell in the Browser

The browser An alternative view of a GoldSim model, in which elements are displayed in a tree, and organized either hierarchically, or by type. view of a Cell pathway A transport pathway element that is mathematically equivalent to a finite difference node. Cells are commonly applied to simulate discrete compartments in an environmental system (such as ponds, lakes, shallow soil compartments, or the atmosphere). is shown below:

Note: Element inputs and outputs are only shown in the browser if you choose to Show element subitems (accessed via the browser context menu by right-clicking in the browser).

The Properties folder contains the basic inputs for the Cell. In particular, it contains the Cumulative Input, Discrete Changes, and the quantities of each of the 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. present. You can create links to these inputs using the Link Cursor A special cursor for creating links invoked by double-clicking on an input or output object in a browser..

Note that the 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). input, and an input for each medium in the cell also appear in the Properties folder. The Species input is automatically linked to the nearest Species element when the Cell is created. The media inputs are automatically created and linked to the corresponding media when they are added to the Cell. These links cannot be changed, and are displayed for information purposes only.

The pathway's mass and concentration outputs are then first. Note that in the example shown above, the Cell contains two media: Water (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).), and Sediments.

If the Cell has any mass flux links associated with it, the corresponding inputs and outputs for these links are organized into the Inflows, Outflows, Diffusive Influxes, and Diffusive Outfluxes folders. Note that these folders are not shown if they are empty.
