Advanced Axisymmetric Nonlinear Contact dialog box (Simcenter Nastran)

Type
Type list	Defines the type of contact to create.Flexible 2D Contact — The target contact region is flexible.Rigid 2D Contact — The target contact region is a sequence of nodes that are not connected to elements, that represents a rigid surface. You can tie all nodes on the target to a master node (which you define in Master Grid Point). For example, you might use this method to model a steel die stamping a softer metal.
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.
Source Region
Select Object	Lets you select the contacting nodes in the contact pair. For more information, see BLSEG in the Simcenter Nastran Quick Reference Guide.
Target Region
Available when Type is set to Flexible 2D Contact.
Select Object	Lets you select the contacted nodes in the contact pair.For more information, see BLSEG in the Simcenter Nastran Quick Reference Guide.
Rigid Target (Ordered Nodes)
Available when Type is set to Rigid 2D Contact.
Select Object	Lets you select a sequence of unconnected nodes to define as the rigid target region. The nodes you select for the rigid target region must not be connected to elements. The sequence in which you select the nodes determines the contact side of the target region. You can override this target contact side using the Rigid Contact Target Side option.
Master Grid Point (MGP)
Valid only when Type is set to Rigid 2D Contact.
Select Object	Lets you select a single node or point as a “master” node to control the motion of the rigid target contact region. Internally, rigid links connect all the nodes on the rigid target region to this master node. You can assign a displacement constraint or load to this master grid point and the entire rigid target region moves with it.
Contact Set Parameters (BCTSET)
Coefficient of Static Friction	Defines the friction for this contact pair.For more information, see BCTSET in the Simcenter Nastran Quick Reference Guide.
Contact Region Parameters (BCRPARA)
Rigid Contact Target Side (SURF)	Available only when Type is set to Rigid 2D Contact. Defines the contact side for the target region, overriding the contact side that is determined by the node selection in the target region.For more information, see BCRPARA in the Simcenter Nastran Quick Reference Guide..
Source Offset****Target Offset	Defines the offset distance for the contact region. You can use these options to model an interference condition.For more information, see BCRPARA in the Simcenter Nastran Quick Reference Guide.
Contact Set Parameters (BCTPARA)
Parameter Reference	The name of the BCTPARA modeling object to use with this contact set.
Create Modeling Object	Opens the Contact Set Parameters dialog box, where you can define the parameters for the BCTPARA modeling object.For more information, see BCTPARA in the Simcenter Nastran Quick Reference Guide..
