Unit Force dialog box

Name
Name	Sets the name of the Unit Force excitation to compute a frequency response function (FRF) using a SOL108 Direct Frequency Response Functions or SOL111 Modal Frequency Response Functions solutions.
Description	Sets the description for the unit force excitation.
Destination Folder
Load 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 existing folders.To create a new folder, right-click any level of the hierarchy and choose New Folder.
Model Objects
Group Reference	Lets you apply the unit force excitation to a group.For more information, see Group Reference options.
Select Object	Lets you select the geometry or FE entities on which the load will be applied.ExcludedLets you remove individual FE entities from within the 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.
Degrees of Freedom
DOF1 through DOF6	Specifies the degrees of freedom (DOFs) that you want to excite.DOF1 to DOF3 are for translation in the X, Y, and Z direction.DOF4 to DOF6 are for rotation in the X, Y, and Z direction.
No DOFs Excited	Sets all DOF to Not Excited.
All DOFs Excited	Sets all DOF to Excited.
