Immersed Ducts dialog box (Thermal/SST/ESC/Multiphysics)

Name
Name Defines the simulation object name.Description opens a text 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 list of folders you can use to store the boundary conditions.To create a new folder, right-click any level of the hierarchy and choose New Folder.
Fluid Ducts
Group Reference Applies immersed ducts boundary condition to the selected group. For more information, see Group Reference options.
Select Object Lets you select the 1D duct elements, curves and polygon edges to define a fluid duct.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
Heat Transfer Coefficient Sets a value for the heat transfer coefficient between 1D duct elements and 3D solid elements.For more information, see Additional magnitude options.
