To start a parametric analysis go to the Simulation screen and click on the Parametric tab. Calculations are updated using the Update toolbar icon in the usual way. The data on the Parametric Analysis Calculation Option dialog is used to provide options to control the analysis as well as outputs to help you to understand the progress being made as the calculations continue.
Note: It is necessary to run the base simulation with monthly/annual outputs before opening the Parametric tab. The parametric simulations will all be run using the base calculation and model options. So the simulation period and all other options used in the analysis are the same as those defined on the Simulation calculation options dialog.
There are 2 tabs on the Dialog:
