Duct Flow Boundary Conditions dialog box – Duct Total Pressure options

Option Description
Name Defines the simulation object's name.Description opens an editor that lets you type a description for the simulation object.
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 Lets you apply the duct total pressure to a group.For more information, see Group Reference options.
Select Object Lets you specify the point, mesh point, or node within a duct network at which to define the fluid pressure.Excluded lets you remove individual entities from within your selected object.
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.
Magnitude
Total Pressure-Gauge Sets the total gauge pressure value to define a pressure at the duct opening.For more information, see Additional magnitude options.
