When you are creating and editing models using the Multi Scenario modeling option, the following rules apply with respect to inheritance of common properties, and propagation of editing operations. There are THREE levels:
All Groups / Scenarios
Master Scenario + Additional Scenarios
All changes made to a Master Scenario are automatically propagated to all other scenarios in the same group. Therefore you should only edit a Master Scenario when you wish to propagate the changes to all other scenarios in the group.
Shared by all groups / scenarios
The following properties are shared by ALL groups and scenarios.
Soil Profile Boundaries and Material Assignments
All Units (general, permeability)
All Functions defined in properties and groundwater (user defined bcs, discrete functions, etc.)
The following properties are shared by all scenarios in a given group.
Editing of external and material boundaries
Slope failure direction
Individual scenarios can be edited independently of each other, with the exception of the shared properties of groups / scenarios listed above, and the Master Scenario.
If you wish to propagate edits from one scenario to all other scenarios in a group, edit the Master Scenario.
If you wish to propagate edits from one scenario to selected scenarios in a group, then use the Link Scenarios option. This will propagate all applicable editing options to only the selected scenarios in a group.
NOTE: the following editing options are not propagated between scenarios:
All mesh operations (mesh/discretize, increase density, etc.)
Addition/deletion of groundwater boundary conditions
Display settings (these can be set to apply to all scenarios in the display options dialog or the sidebar)
These options are NOT synchronized between scenarios in the same group, even when Link Scenarios is turned on, and will have to be applied individually to each scenario.
