Contact dialog box (LS-DYNA)

Type	Specifies the general type of contact to define.Select Automatic Contact to use an improved, more robust algorithm to calculate contact. With the automatic contact types, LS-DYNA can detect penetration coming from either side of a shell element. Select Tied Contact to tie the slave side of the contact to the master side by constraining the translational degrees of freedom where contact occurs.Select Other Contact to define specialized types of contact or to create a user-defined contact definition.
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.
Contact Type
Contact Type	Specifies the type of contact to define. The types available depend on the general contact type you select at the top of the dialog box.For more information, see Supported LS-DYNA contact types.
Slave Region****Master Region
Slave Segment Type****Master Segment Type	Controls how you specify the elements on the both sides of the contact definition.Select *PART to select a PART type of physical property table. If the region contains many PART physical property tables, the software only writes out the first PART property table it finds. If you want to select multiple PART physical property tables, select the *SET_PART option instead.Select *SET_PART to select multiple PART physical property tables.Select *SET_SHELL to write select a Region that includes all the appropriate 2D elements.Select *SET_SEGMENT to use a SET_SEGMENT modeling object to define the appropriate elements. A segment is a facet defined by an element's face. A set of segments is similar to a group of nodes or elements but with additional contact properties.Select *PART (Contact Region) to select a Region that contains the appropriate elements. Use this option if you want to define a Region that contains elements from a single physical property table. If you want to select elements that use multiple PART physical property tables, select the *SET_PART (Contact Region) option instead.Select *SET_PART (Contact Region) to select a Region that contains the appropriate elements. Use this option if you want to define a Region that contains elements from multiple physical property table.
Slave Region Master Region	Lets you select the region that contains the elements or faces to define the slave or master surface in the contact definition.For more information on regions, see Working with reusable regions.
Slave Segment Properties Master Segment Properties	Available if you select *SET_SEGMENT from the Slave Segment Type or Master Segment Type lists.Lets you create or specify the SET_SEGMENT modeling object to use to define the segment and its properties. In LS-DYNA, contact segments are composed of the faces of elements included in a contact definition.
**Include All Slave Nodes in a Box (SBOXID)**Include All Master Segments in a Box (MBOXID)	When you define the slave region, lets you analyze contact using only those slave nodes/segments that lie within the defined box. When you define the master region, lets you analyze contact using only those nodes and elements in the specified master region that lie inside a defined box.With this option, LS-DYNA only considers the nodes or nodes and elements in the specified region that also lie inside the defined box when it calculates contact.
Box Diagonal First Corner****Box Diagonal Second Corner	Lets you specify the first and second corners that define the box.
Swap Regions
	Available if you select Tied Contact at the top of the dialog box.Reverses the master and slave regions.
Contact Properties
Card 2/Card 3	Lets you specify a required Contact Card 2 Card 3 modeling object to set additional, required contact parameters.For more information, see Specifying additional LS-DYNA contact properties.
Card A/Card B (optional)	Lets you specify a Contact Card A Card B modeling object to set additional, optional contact parameters.For more information, see Specifying additional LS-DYNA contact properties.
Massively Parallel Processing (MPP) Cards	Lets you specify a Contact MPP Cards modeling object to control how the MPP version of LS-DYNA performs contact calculations. In the MPP version of LS-DYNA, contact calculations are distributed between the available processors.For more information, see Specifying additional LS-DYNA contact properties.
