Menus & Buttons : Simulation > Update

Commit all parameter values to your model. This is a good way to keep all aspects of the modelling environment integrated.

Some of your settings take immediate effect, e.g., your grid dimensions are immediately used by the GIS Control, but many parameter values and settings only become "active" after you have updated your model. If in doubt then update. The only disadvantage is needing to wait while it happens, which can be a little while for large grid models with a lot of GIS data, but make sure you also read the notes on optimizing your GIS inputs.

The first thing to happen on running your simulation is your model is updated with any changes to your parameter settings.

For more information please read the detailed notes on simulations and the simulation process.
