Viewing a Pipe 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 Pipe pathway A transport pathway element that is intended to represent a feature that essentially behaves as a fluid conduit, such as a fracture. Pipes are primarily used for simualting matrix diffusion in fractured groundwater pathways. 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 all the inputs for the Pipe. The Properties folder contains the basic inputs for the Pipe, including the two subfolders containing the matrix A two-dimensional array. diffusion zone and stagnant zone properties. (Note that these subfolders are not shown if these zones are not being simulated.) With two exceptions (listed below), you can create a link to any of these property inputs.

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 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). input also appear in the Properties folder. The Species input is automatically linked to the nearest Species element when the Pipe is created. Similarly, the Reference Fluid input is automatically linked to the nearest Reference Fluid element when the Pipe is created. These links cannot be changed, and are displayed for information purposes only.

If Matrix Diffusion or Stagnant Zones exist, subfolders are added for these. The Inflows and Outflows folders contain all of the mass flux links for the Pipe.

The pathway's mass and concentration outputs are listed first. Note that for a Pipe, the concentration always refers to that in the Reference Fluid.

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