Enforced Speed Constraint dialog box (Simcenter Samcef)

Type
Type	Specifies how the enforced speed constraint is defined:ComponentsLets you define a constraint by specifying a magnitude for the individual degrees of freedom.Magnitude and DirectionLets you define the constraint by specifying the magnitude in a single direction.NormalLets you define the constraint by specifying a magnitude and a +/– direction that is normal to the selected geometry or element faces.Translational components – FieldLets you define the constraint as a constraint magnitude for the translational degrees of freedom only.
Name
Name	Sets the name of the constraint.
Description	Sets the description of the constraint.
Destination Folder
Constraint 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 constraint to a group.For more information, see Group Reference options.
Select Object	Lets you select the objects on which the constraint will be applied. ExcludedLets 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
Appears when Type is set to Magnitude and Direction or Normal.
Speed	Defines the magnitude of the enforced speed.For more information, see Additional magnitude options.
Degrees of Freedom
Appears when Type is set to Components or Translational Components – Field.
DOF1 through DOF6	Specifies the magnitude of the enforced speed for each of the DOF:ExpressionLets you define the enforced speed magnitude for each DOF with a constant value or expression.FieldLets you define a varying enforced speed magnitude. Use the Scale Factor option to apply a uniform scale factor to the magnitude of the enforced speed at each DOF. For more information, see Additional magnitude options.
Distribution
Appears when Type is set to Magnitude and Direction, Components or Normal.
Method	Defines how the enforced speed constraint is distributed over the selected objects.ConstantApplies the magnitude to the object as a constant value.SpatialUses a unitless field to map the enforced speed constraint to the model.Note: A field is always mapped to global or Cartesian coordinates, even it if was defined in cylindrical or spherical coordinates.
Distribution Field
Appears when Method is set to Spatial.
Specify Field	Defines how the enforced speed constraint is distributed over the nodes or elements in the selected area.
Direction
Appears when Type is set to Magnitude and Direction, Components or Translational Components – Field.
Specify Vector	Appears when Type is set to Magnitude and Direction.Lets you select or create a vector the defines the direction in which to apply the constraint.
Displacement CSYS or Velocity CSYS	Appears when Type is set to Components or Translational Components – Field.Sets the coordinate system used to apply the constraint. You can use the Existing coordinate system currently defined for the selected nodes or geometry, or select one of the following local coordinate systems: Cartesian, Cylindrical, Spherical.
