Reordering Species

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). are added to the species list shown in the Species dialog in the order that they are created. This is also the default order that they appear in the species array label set A special set of array labels that can only be populated and edited via the Species element.. (The order that they appear in the species array A collection of variables that share common output attributes and can be manipulated in GoldSim elements or input expressions. label set is indicated by the Row #). In some situations, however, you may want to change the order in which the species appear in the species array label set.

You can reorder the species via the Species set ordering drop-list:

As can be seen, this allows you to sort the species alphabetically or by Molecular Weight. The final option in this list, "User-defined", allows you to manually move items up and down the list. If this option is selected, the Row Up and Down buttons at the bottom of the page become active:

Selecting a row and pressing one of these buttons moves the species up or down in the list.

Note: If you reorder the species, any existing elements using the species array label set will automatically be re-sorted to the new sequence.

Note that changing the set order does not actually change how the species are displayed in the Species dialog. It simply changes the Row # (and hence the order that the species appear in the species array label set).

By default, when you open the Species dialog, the species will always be displayed alphabetically. You can, however, change how they are displayed in the dialog. You do so by clicking on the column headers. For example, clicking on the ID column header sorts the species alphabetically (in ascending order). Clicking it again sorts in descending order. It is important to note, however, that sorting the species by clicking on the column headers in this way does not actually reorder the species in terms of the order of items in the species array label set. It is simply for display purposes while you are in the Species dialog. The Row # indicates the actual order of items used in the species array label set, and this can only be changed via the Species set ordering drop-list.

While viewing the species, you can also quickly jump to a particular row by placing your cursor in a column and typing the first letter (or number) of a search string. GoldSim will jump to the first corresponding row that it finds.

Note: Although you can reorder the species array label set as described above, the elements array label set is always alphabetical.
