Transient Initial Conditions dialog box

Type
Type	Specifies how the constraint is defined:Magnitude and Direction — Lets you define a displacement and velocity magnitude in a single direction.Normal — Lets you define a displacement and velocity magnitude and a +/– direction normal to the selected geometry or element faces. Components — Lets you define the initial displacement and velocity magnitudes for each of the six degrees of freedom (DOF).
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.
Folder Manager	Displays a hierarchical listing 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 constraint to a group.For more information, see Group Reference options.
Select Object	Lets you select the geometry, node, element, or other FEM object on which the constraint will be applied. ExcludedLets you remove individual 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.
Direction
Specify Vector	Appears only when the Magnitude and Direction type is selected.Defines the direction of the constraint. The software creates a displacement coordinate system if the vector does not match the work coordinate system Z direction.
Reverse Direction	Appears only when the Magnitude and Direction type is selected.Reverses the direction of the vector.
Displacement CSYS	Appears only when the Components type is selected.Sets the coordinate system that the software uses to apply the constraint. You can select the Global Cyclic Analysis or the Existing coordinate system currently defined for the selected nodes or geometry, or you can create one of the following types of local coordinate systems: Cartesian, Cylindrical, Spherical.Note: The Global Cyclic Analysis coordinate system is available only if it is defined in the FEM.
Local	Lets you create or select a local coordinate system.
Magnitudes
Appears only when the Magnitude and Direction or Normal type is selected.
Initial Displacement	Lets you define the magnitude of the initial displacement.For more information, see Additional magnitude options.
Initial Velocity	Lets you define the magnitude of the initial velocity.For more information, see Additional magnitude options.
Initial Displacement
Appears only when the Component type is selected.
DOF1 through DOF6	Defines the magnitude of the initial displacement for each of the DOF with a constant value or expression.For more information, see Additional magnitude options.See Expressions for more information.
Initial Velocity
Appears only when the Component type is selected.
DOF1 through DOF6	Defines the magnitude of the initial velocity for each of the DOF with a constant value or expression.
Magnitudes
Initial Displacement	Defines the magnitude of the initial displacement as a constant value or expression.For more information, see Additional magnitude options.
Initial Velocity	Defines the magnitude of the initial velocity as a constant value or expression.For more information, see Additional magnitude options.
Distribution
Method	Defines how the initial conditions are distributed over the selected objects.ConstantApplies the magnitude to the object as a constant value. SpatialUses a unitless field to map the constraint to the nodes. A field is always mapped to global or Cartesian coordinates, even if it was defined in cylindrical, or spherical coordinates, or in parametric space.
Distribution Field
Appears only when the Spatial distribution method is selected.
Card Name	Displays the name of the solver card for the constraint.
