InfoWater Pro Multi-Species Model (MSX) provides a user-friendly approach to build advanced water quality models.
InfoWater Pro versions up to 2024.3 use the original EPA MSX engine, while versions 2024.4 and up use MSX 2.0 which includes dispersion and improved water quality mass balance and reporting.
To set up a complete multi-species simulation from start to finish, see Set up and Run a Multi-Species Extension (MSX) Simulation.
To display the MSX dialog box, you should follow these steps:
- Go to Command Center in the Model Explorer.
- Click Tools menu.
- Select
Multi-Species Model.
- The Multi-Species Model dialog box displays. You can choose a model from the Multi-Species (MSX) Model dialog box as described below.
The Multi-Species Model parameters can be specified for individual pipes and tanks to override the global values. Also, initial quality values for species can be assigned to both pipes and tanks. Some nodes can also be specified as sources of individual species.
Each icon/tool button of the Multi-Species Model dialog box is described below:
Model – Name of Multi-Species Model.
There are seven example models that are already built into InfoWater MSX: CHLORAMINE, DBP, INACTIVATION, PSM1, PSM2, Temperature, and Turbidity.
Description – Description of the Multi-Species Model.
Note – Notes to describe the details of the active model.
