Flow Boundary Condition dialog box – Convective Outflow options

Name
Name Sets a name for the simulation object.Description opens an editor that lets you type a description for the boundary condition.
Destination Folder
Simulation Object Container Specifies the folder in the Simulation Navigator in which the boundary condition will be stored. The list includes the root container and existing folders that you created using the New Folder command. Examples of a root container include Load Container, Constraint Container, and Simulation Object Container.
Folder Manager Displays a hierarchical listing of existing folders. To create a new folder, right-click any level of the hierarchy and choose New Folder.
Region
Group Reference Applies the convective outflow boundary condition to the selected group.For more information, see Group Reference options.
Select Object Lets you select the faces or elements on the boundary of the flow domain to model fluid as an outlet boundary condition without specifying the pressure.Excluded lets you remove individual entities from within your selected object. The software does not apply the simulation object to the excluded elements.Note: The Element Selection Filtering options are available when the Type Filter list on the Top Border bar is set to Elements.
Stacked Smart Selector Methods Opens the Smart Selector Methods dialog box where you can specify a progression of smart selection filters.For more information, see Smart Selector Methods dialog box.
