Abaqus/CAE creates contact interactions and tie constraints for every item in the contact pair candidates table based on the parameters you have specified.
To create contact interactions and tie constraints:
From the main menu, select either Interaction
Find contact pairs or ConstraintFind contact pairs.
Tip:
You can also find contact pairs using the 
tool in the Interaction module toolbox.
Abaqus/CAE displays the contact detection dialog box.
Enter the search parameters as described in “Specifying search criteria for contact detection,” Section 15.16.1.
Perform a search for contact pairs as described in “Performing a search for contact pairs,” Section 15.16.2.
In the contact pair candidates table, enter all of the parameters necessary to define the interactions and ties as described in “Reviewing and modifying detected contact pairs,” Section 15.16.3.
Click OK.
Abaqus/CAE creates the specified contact interactions and tie constraints.
