Bolt Contact with Clearance dialog box (Abaqus)

Type
Type	Specifies the face pair creation method to use to identify the contacting surfaces.Automatic PairingCreates face pairs automatically using the Create Automatic Face Pairs dialog box.ManualLets you create face pairs manually by selecting a Master Surface and a Slave Surface.
Destination Folder
Simulation Object 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.
Automatic Face Pair Creation
Create Face Pairs	Appears when the face pair creation method is set to Automatic 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.
Master Surface/Slave Surface
Master Surface/Slave Surface	Appears when the face pair creation method is set to Manual.Lets you select the Region that defines the contacting (master) and contacted (slave) surface in the contact pair. The master face defines the direction for the contacts that get created.Note: The master and the slave surfaces must contain the same type of entity (that is, faces, element faces, and so on).Select an existing region or click New Region to create a new region. See Region dialog box.
Swap Regions
	Reverses the master and slave surfaces. The master and the slave surfaces must contain the same type of entity (that is, faces, element faces, and so on).
Clearance Definition
Value	Defines the clearance or overclosure value as either uniform or spatially varying for the contact pair. For more information, see Additional magnitude options.If you select Expression, you can specify a uniform clearance or overclosure value for the contact pair. A positive value indicates a clearance value, and a negative value indicates an overclosure value.If you select Field, you can specify spatially varying clearances or overclosures. With this option, you use a table field to specify the clearance at a single node or set of nodes on the slave surface. In the table field, the node ID is the independent variable, while the clearance or overclosure value is the dependent variable. You can also specify a Scale Factor to apply to the field. For more information, see Fields.
Scale Factor	Appears when Value is set to **Field.**Scales the clearance or overclosure by the specified value.
Half-thread Angle	Specifies the half-thread angle for the bolt. For more information, see Bolt Contact with Clearance (Abaqus).
Pitch	Specifies the pitch (the thread-to-thread distance) for the bolt.
Bolt Thread Diameter	Controls whether you specify either the bolt's major or mean thread diameter in the Diameter box.
Diameter	Specifies the diameter of the bolt.
Contact Pair
Contact Pair	Lets you select or create a Contact Pair modeling object to define properties for the pairs of surfaces that may contact or interact during the analysis.For more information, see Defining contact pairs (Abaqus Structural and Thermal analyses).
Boundary Condition Generation
Associate to Automatic Pair Recipe	Appears when the face pair creation method is set to Automatic Pairing.Specifies whether automatically generated face pairs are associated with the automatic pair recipe. The automatic pair recipe is the set of parameters on the Create Automatic Face Pairs dialog box that determine how to compute and group face pairs. When this option is selected, the generated pairs appear in the Simulation Navigator with the prefix Auto. If the master part updates, the software recalculates the face pairs and updates the boundary condition.When this option is cleared, the generated contact pairs are not associated with the face pair recipe. If the master part updates, the software does not update the contact pairs. These contact pairs behave the same as manually created pairs.
