Names are provided for the contact pair and any created surfaces. Table 1 outlines the naming algorithm.
Use the Names tabbed page before performing a search to modify the naming prefix and control the creation of surfaces. For details, see Specifying naming options for contact detection. The default parameters supplied to contact pairs by the contact detection tool are slightly different than the defaults used in the traditional interaction or constraint editor. Most notably, the contact detection tool initially assigns surface-to-surface discretization to each contact pair instead of node-to-surface discretization. See Mesh tie constraints, and Contact formulations in Abaqus/Standard, for a discussion of surface discretization and the associated constraint enforcement methods. The default surface adjustment options depend on the separation between the surfaces in a contact pair. You can use the Rules tabbed page before performing a search to control the default adjustment options that are assigned to detected contact pairs. You can also use this page to specify a separation tolerance within which all contact pairs default to tie constraints. For more information about the Rules page, see Defining default contact pair parameters. Table 2 lists the default contact pair parameters supplied by Abaqus/CAE. You can edit each parameter individually before creating interactions and constraints. For detailed instructions on editing parameters and defaults, see Reviewing and modifying detected contact pairs.
Note: Some of the parameters discussed above are not visible in the contact pair candidates table by default. Click mouse button 3 anywhere in the table, and select Edit Visible Columns to control which parameters appear in the table.
