Enforced Acoustic Pressure dialog box (Simcenter Nastran)

Name
Name	Sets the name of the enforced acoustic pressure.
Description	Sets description for the enforced acoustic pressure.
Destination Folder
Load Container	Specifies the folder in the Simulation Navigator in which to store the enforced acoustic pressure boundary condition.The list includes the root container and folders that you created using the New Folder command in the Load Container.
Folder Manager	Displays a hierarchical list of folders.To create a new folder, right-click any level of the hierarchy and choose New Folder.
Model Objects
Group Reference	Lets you select the groups of fluid nodes to apply the enforced acoustic pressure.For more information, see Group Reference options.
Select Object	Lets you select the nodes or polygon faces on which the software applies the load. If you select polygon faces, the software applies the acoustic pressure load to all the fluid nodes associated with the selected faces.
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.
Excluded	Lets you remove individual entities from within the selected object.Select Object: Lets you select the geometry or FE entities from which the enforced acoustic pressure will be removed. You can select it by using the Excluded icon.
Magnitude
Specifies the constant complex excitation with real and imaginary parts, constant complex excitation with magnitude and phase angle, or the frequency dependent complex field values.
Format	Specifies how the excitation is defined.
Real	Available only when Format is set to Real/Imaginary.Sets the real component of the magnitude of the excitation.
Imaginary	Available only when Format is set to Real/Imaginary.Sets the imaginary component of the magnitude of the excitation.
Magnitude	Available only when Format is set to Magnitude/Phase.Sets the magnitude of the excitation.
Phase	Available only when Format is set to Magnitude/Phase.Sets the phase angle of the excitation.
Specify Field	Available only when Format is set to Field.Specifies the frequency dependent complex field values.Options include:Select Existing Field from List opens the Fields dialog box, where you can select a field.A field can define a magnitude that varies with independent variables such as frequency, temperature, or time. For more information about fields, see Fields.Formula Constructor opens the Formula Field dialog box, where you can define a formula to construct a field.For more information, see Define a boundary condition using a formula field.Table Constructor opens the Table Field dialog box, where you can define tabular data to construct a field.Plot (XY) plots the field as an XY graph.For more information, see Graph overview.Overlay (XY) overlays a plot on an existing plot. You can overlay up to 50 plots.For more information, see Overlay plots.
