Enforced Acceleration Load dialog box (Simcenter Samcef)

Use this dialog box to define how to apply the load and to set a coordinate system and acceleration value to apply to any DOF. You can use enforced acceleration loads in dynamic response analyses (Linear Transient Response Analysis and Linear Harmonic Response Analysis).

Type	Specifies how the enforced acceleration load is defined.ComponentsLets you define the load by specifying a magnitude for the individual degrees of freedom or for specified nodes and their degrees of freedom.Magnitude and DirectionLets you define the load by specifying the magnitude in a single direction.NormalLets you define the load by specifying a magnitude and a +/– direction that is normal to the selected geometry or element faces.
Name
Name	Sets the name of the load.
Description	Sets the description of the load. The description appears in the Information window.
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.To view a hierarchical list of existing folders, click Folder Manager . To create a new folder, right-click any level of the hierarchy and choose New Folder.
Model Objects
Group Reference	Lets you apply the load to a group.For more information, see Group Reference options.
Select Object	Lets you select the objects on which the load will be applied.
Stacked Smart Selector Methods	Opens the Smart Selector Methods dialog box where you can specify a progression of smart selector filters to select objects.For more information, see Stacked smart selector methods.
Excluded	Lets you remove individual entities from within your selected object.
Direction
Appears when Type is set to Components or Magnitude and Direction.
Displacement CSYS	Appears when Type is set to Components.Specifies the coordinate system used to apply the load.You can use the existing coordinate system that is currently defined for the selected objects, or you can select a local coordinate system.
Local	Appears when Displacement CSYS is set to Cartesian, Cylindrical, Spherical.Lets you create or select a local coordinate system.See CSYS dialog box for more information.
Specify Vector	Appears when Type is set to Magnitude and Direction.Lets you select or create a vector that defines the direction in which to apply the load.
Magnitude
Appears when Type is set to Magnitude and Direction and Normal.
Acceleration	Defines the magnitude of the enforced acceleration.For more information, see Additional magnitude options.
Degrees of Freedom
Appears when Type is set to Components.
Unique DOF Values	Lets you select the nodes to which you want to apply the DOF.
Edit per Node	Appears when the Unique DOF Values check box is selected.Opens the Edit by Label dialog box from which you can set the magnitude value for the degree of freedom for each independent node.
DOF1DOF2DOF3DOF4DOF5****DOF6	Appears when the Unique DOF Values check box is cleared.Specifies the magnitude of the acceleration load for each DOF:ExpressionLets you define the enforced acceleration for each DOF with a constant value or expression.For more information, see Additional magnitude options.
