Groups and Scenarios

When you enable the Multi Scenario modeling option, a Document Viewer pane will appear in the sidebar. The Document Viewer allows you to create and organize the various Slide models that you wish to analyze, by defining multiple groups and / or scenarios.

By default, when you initially enable Multi Scenario modeling, one Group containing one Master Scenario will automatically be created. New groups or scenarios can be easily created, copied and edited as required. This is all done within the umbrella of a single (compressed zip) document which can be edited, saved and computed as a single file (file extension *.slmd).

The properties of groups and scenarios are described below.


A Group allows you to group together multiple models (scenarios) that have the same boundaries or other common input parameters.

Master Scenario

When you create a Group, a Master Scenario is automatically created. The properties of the Master Scenario are as follows:

Additional Scenarios

In addition to the Master Scenario, any number of additional Scenarios can be created within a Group.

Link Scenarios

By default, individual scenarios can be edited independently of each other, with the exception of the shared properties of groups / scenarios. The Link Scenarios option allows you to propagate applicable editing options from one scenario to any other scenarios in a group. Link Scenarios can be selected from the sidebar or the toolbar.

The following actions are NOT propagated even if Link Scenarios is selected.

When Link Scenarios is turned on, these options are NOT synchronized between scenarios in the same group, and will have to be applied individually to each scenario.

Add / Duplicate / Delete
