The Contact page in the Job Diagnostics dialog box displays information about regions of the model where changes in the contact status prevent ABAQUS from accepting the solution.

Contact information is available for any iterations that are followed by (SDI) (Severe Discontinuity Iteration) in the Job History tree. Contact information may also be available for other iterations where contact impacts the analysis, such as when stick-slip friction behavior is present. Use the contact information to locate regions in your model where ABAQUS could not establish the correct conditions. You may need to edit the contact controls to resolve a contact problem. For more information, see “Customizing contact controls,” Section 15.11.4.

Select Highlight selections in viewport to locate problematic regions of your model in the current viewport. Your selections in the Contact Diagnostics and Details fields determine the region of the model that will be highlighted in the viewport and the type of diagnostic information that is associated with the highlighted region.
