Define surface-to-surface contact

You define surface-to-surface contact by creating face pairs. You can define face pairs for surface-to-surface contact automatically or manually.

Define contact regions automatically

Lets you select the region that defines the contacting surface in the surface pair. The first surface defines the direction for the contacts. Select an existing region or click New Region to create a new region. See Working with reusable regions.

1. Choose Home tab→Loads and Conditions group→Surface-to-Surface Contact .

2. In the Surface to Surface Contact dialog box, from the Type list, select Automatic Pairing.

3. In the Automatic Face Pair Creation group, click Create Face Pairs .

4. In the Create Automatic Face Pairs dialog box: (Optional) Specify a Face Pair Search Subset.Select a Grouping Option.Preview the face pairs, and if necessary, modify the distance tolerance to generate more or fewer pairs.For more information, see Create Automatic Face Pairs dialog box.

5. Click OK to return to the Create Surface-to-Surface Contact dialog box.

6. In the Properties group, enter any solver-specific properties for the contact between these face pairs and click OK.

Define contact regions manually

1. Choose Home tab→Loads and Conditions group→Surface-to-Surface Contact .

2. In the Surface to Surface Contact dialog box, and from the Type list, select Manual.

3. In the Source Region group, select the first set of surfaces or element faces.

4. In the Target Region group, select the second set of surfaces and element faces.

5. In the Properties group, enter any solver-specific properties for the contact between these face pairs and click OK.
