Scenarios are used for running a sequence of simulations, typically when you want to use the same [[model]] for different sets of input data - perhaps for different geographical locations. 

You can also use scenarios to experiment with solver settings or to run a sequence of different sensitivity analyses. 

====Defining scenarios====

Scenarios are defined and listed in the [[context screen]] behind the **[[context screen#scenarios|scenario]]** button. 

This panel allows you to create a list of scenarios and to select which parameters/lookup tables have different data for different scenarios. The actual data is then entered in the [[time series screen]] and [[parameters screen]] respectively. 

This panel also let you specify individual settings for each scenario.
