This workspace contains several instances of the Weinstein model. There is the general description of the mathematical model and then that model instantiated into specific simulation experiments to reproduce each of the original figures. These models can be browsed via the *Navigation* panel in the right hand column.

- NHE3 Model is the general NHE3 model and can be imported to use in any other model.
