The first step in defining an RT3D simulation is to define the data required by the Basic Transport (BTN) package. The options in the Basic Transport Package dialog unique to RT3D are as follows:
The Packages button brings up the Packages dialog. If the RT3D model is the current model and the Chemical Reaction package is selected, one of the RT3D reactions must be selected from the pull-down list. The first nine reactions are pre-defined reaction types. If one of these reactions is selected, the names of the species and the names of the reaction parameters are automatically determined by GMS. The last reaction is a user-defined reaction. If this option is selected, a list of species and list of reaction parameters must be specified by the user.
For most of the reaction package options, once the reaction package is selected, the list of species used by the package is automatically initialized by GMS. However, if the user-defined reaction package is selected, the Define Species button is undimmed in the Basic Transport Package dialog and a list of species must be manually defined before any concentrations are assigned to sources/sinks.
