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 Fluid is shown below:
Note that 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). appears as an input. This input is automatically linked to the Reference Fluid (or the nearest clone of the Reference Fluid) when the Fluid is created. This link cannot be changed using the Link Cursor A special cursor for creating links invoked by double-clicking on an input or output object in a browser., and is displayed for information purposes only.
The other three inputs to the Fluid can be specified as links. The Relative Diffusivities and 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. (or alternatively, Solubilities) are vectors (by element), and hence can be expanded:
A Fluid has a single output (and hence has the same ID as the medium). The Fluid output expands to reveal the medium properties, as shown below:
That is, the three properties that you enter for a Fluid are "passed through" the element and become outputs which you can then link to other elements.
You can save these results by clicking Final Values and/or Time Histories in the editing dialog for the Fluid. Checking one of these causes all three outputs to be saved as results. If you wish to save only one or two of these as results, you can use the context menu of the output (accessed via a right-click) in the browser to turn on or off one or more of the three outputs. In this case, the checkbox in the editing dialog would become gray (indicating that some of the results will be saved).
