Specific Duct Mode / Distributed Duct Mode / Anechoic End dialog box

Specific Duct Mode dialog box

Name
Name	Sets the name of the duct mode.
Description	Sets a description for the duct mode.
Destination Folder
Load Container	Specifies the folder in the Simulation Navigator in which to store the duct mode load.The list includes the root container and any folders that you optionally created in the Load Container.
Folder Manager	You can optionally create a hierarchy of folders to store and organize your loads in the Load Container. To create a new folder, right-click any level of the hierarchy and choose New Folder.
Location
Duct Region	You will create and select a Duct inlet region. A Duct inlet region selects the fluid element faces on a duct inlet to apply the duct modes. It also defines the cross sectional properties for the duct inlet.Select Create Region to create a new Duct inlet region.For more information on creating the region, see Region dialog box.
Duct Mode Amplitude
You will define the duct mode order relative to the two duct cross section directions. In addition, you will define the amplitude as a complex data pair.
Azimuthal / X Order	If your cross section is circular or annular, you specify the order relative to the azimuthal-direction.If your cross section is rectangular, you specify the order relative to the X-direction.
Radial / Y Order	If your cross section is circular or annular, you specify the order relative to the radial-direction.If your cross section is rectangular, you specify the order relative to the Y-direction.
Measure Type	Select the units of the duct mode amplitude as Acoustic intensity, Acoustic power, or Pressure.
Format	Specify the format of the duct mode amplitude complex data pair. You designate the form of this data pair as Real/Imaginary, Magnitude/Phase, or Field.
Real	Specifies the real value of the amplitude complex data pair when Format is Real / Imaginary.
Imaginary	Specifies the imaginary value of the amplitude complex data pair when Format is Real / Imaginary.
Magnitude	Specifies the magnitude value of the amplitude complex data pair when Format is Magnitude/Phase.For more information, see Additional magnitude options.
Phase	Specifies the phase angle value of the amplitude complex data pair when Format is Magnitude/Phase.
Specify Field	Specifies the frequency dependent complex field values when Format is set to Field.The Scale Factor scales the values defined in the field.
Ancillary Display Options
Controls the display of the duct mode. For more information, see Ancillary Display dialog box (Simcenter Samcef)

Distributed Duct Mode dialog box

Name
Name	Sets the name of the duct mode.
Description	Sets a description for the distributed duct mode.
Destination Folder
Load Container	Specifies the folder in the Simulation Navigator in which to store the duct mode load.The list includes the root container and any folders that you optionally created in the Load Container.
Folder Manager	You can optionally create a hierarchy of folders to store and organize your loads in the Load Container. To create a new folder, right-click any level of the hierarchy and choose New Folder.
Location
Duct Region	You will create and select a Duct inlet region. A Duct inlet region selects the fluid element faces on a duct inlet to apply the duct modes. It also defines the cross sectional properties for the duct inlet.Select Create Region to create a new Duct inlet region.For more information on creating the region, see Region dialog box.

Anechoic End dialog box

Name
Name	Sets the name of the anechoic end duct.
Description	Sets a description for the anechoic end duct.
Destination Folder
Simulation Object Container	Specifies the folder in the Simulation Navigator in which to store the Anechoic End boundary condition.The list includes the root container and any folders that you optionally created in the Simulation Object Container.
Folder Manager	You can optionally create a hierarchy of folders to store and organize your Simulation Objects in the Simulation Object Container. To create a new folder, right-click any level of the hierarchy and choose New Folder.
Location
Duct Region	You will create and select a Duct outlet region. A Duct outlet region selects the fluid element faces on a duct outlet to apply the anechoic end duct. It also defines the cross sectional properties for the duct outlet.Select Create Region to create a new Duct outlet region.For more information on creating the region, see Region dialog box.
Ancillary Display Options
Controls the display of the anechoic end duct. For more information, see Ancillary Display dialog box (Simcenter Samcef)
