Cyclic Symmetry dialog box (Abaqus)

Type
Type	Specifies the segment creation method.Automatic Cyclic Symmetry PairingSelect to use automatic cyclic symmetry, where you select the faces on the source region and the software automatically finds the matching target faces. For more information, see Automatic face pairing and Create Automatic Face Pairs dialog box (Cyclic Symmetry boundary coupling).Manual Cyclic SymmetrySelect to use manual cyclic symmetry pairing, where you manually create and pair the source and target regions.
Destination Folder
Simulation Object Container	Specifies the folder in the Simulation Navigator in which to store the simulation object. 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.
Automatic Face Pair Creation
Face Pairs	Appears when type is set to Automatic Cyclic Symmetry Pairing.Opens the Create Automatic Face Pairs dialog box, which enables you to specify face pair generation properties, preview face pairs, and generate face pairs automatically.
Source Region
Master Region	Appears when type is set to Manual Cyclic Symmetry.Lets you select the Region that defines the source surface in the pair. The source is the independent DOF.Select an existing region or click New Region to create a new region. See Working with reusable regions.
Target Region
Slave Region	Appears when type is set to Manual Cyclic Symmetry.Lets you select the Region that defines the target surface in the pair. The target is the dependent DOF. Select an existing region or click New Region to create a new region. See Working with reusable regions.
Swap Regions
	Appears when type is set to Manual Cyclic Symmetry.Reverses the source and target (master and slave) regions.
Direction
CSYS	Lets you select an existing cylindrical system or create a new one. The coordinate system you select must be cylindrical and its z-axis must be collinear with the global cyclic analysis coordinate system.
Local	Chooses the method for specifying the coordinate system.For more information, see the CSYS dialog box.
Set Displacement CSYS	Instructs the software to assign the designated reference coordinate system to the source and target sources as the nodal displacement coordinate system.
Segments
Appear when type is set to Manual Cyclic Symmetry.
Distance Tolerance	Specifies the tolerance to use to determine the distance allowed between face pairs.
Angle Tolerance	Specifies the tolerance to determine the angle allowed between face pairs.
Calculated Segment Angle	Displays the angle the software computed. For example, if your model is a 20.5° segment, the software displays 20.5.
Calculated Number of Segments	Displays the number of segments the software computed.
Override Calculated Number of Segments (N)	Overrides the values the software calculates for the number of repetitive segments in the 360° structure model and lets you enter your own value in the Number of Segments box.
Number of Segments	Appears when the Override Calculated Number of Segments (N) check box is selected. Lets you specify the number of segments in the 360° structure.This corresponds to the N parameter in the *CYCLIC SYMMETRIC MODEL keyword.
Calculate Segment	Instructs the software to compute the segment properties.
Optional Parameters
Adjust Slave Nodes	Specifies whether to move all tied nodes on the slave surface onto the master surface in the initial configuration, without any strain. YesMoves all tied nodes on the slave surface onto the master surface in the initial configuration, without any strain. NoDoes not move the slave nodes.DefaultDoes not specify the Adjust Slave Nodes value and the software does not write the slave node value.
Use Position Tolerance Computed by Solver	Calculates a cutoff distance used to determine which nodes on the slave surface are tied to the master surface. The calculation of the distance between the slave and master surface for a particular slave node depends shell element thickness, whether the surface is node- or element-based, and the types of surfaces. Slave nodes that do not meet the position tolerance are not tied to the master surface. The default value for this tolerance distance depends on the type of formulation and surfaces used in the constraints.
Position Tolerance	Appears when the Use Position Tolerance Computed by Solver check box is cleared. Specifies the cutoff distance.Corresponds to the position tolerance parameter of the *TIE keyword.
Boundary Condition Generation
Associate to Automatic Pair Recipe	Appears when type is set to Automatic Cyclic Symmetry Pairing.(Optional) Specifies whether to associate the automatically generated face pairs with the automatic pair recipe.Note: The automatic pair recipe is the set of parameters on the Create Automatic Face Pairs dialog box that determines how to compute and group face pairs. When the Associate to Automatic Pair Recipe check box is selected, the generated contact pairs appear in the Simulation Navigator with the prefix Auto. If the master part is updated, the software recalculates the face pairs and updates the boundary condition. When the Associate to Automatic Pair Recipe check box is cleared, the generated contact pairs are not associated with the face pair recipe. If the master model changes, the software does not update the contact pairs. These contact pairs behave the same as manually created contact pairs.

These options are available when you click More Options .
Find	Lets you search for an object by typing the full name of the object. For example, to find a group named ABC_group, you must type ABC_group into the search box.After typing the name, press Enter or click Find . If the object is found, it is selected automatically.
Filter by Name	Lets you filter the list by the names of the objects. This filter supports wildcards. The default wildcard of * displays all entries in the list. For example, to filter the list to display every object with a name starting with the letter "a," enter a* as the filter string.
Filter by Label	Lets you filter the list by the names or labels of the objects. This filter supports wildcards. The default wildcard of * displays all entries in the list. For example, to filter the list to display every object with a name starting with the letter "a," enter a* as the filter string.
