Description: When creating a general contact definition for coupled Eulerian-Lagrangian analyses in Abaqus/CAE, you can include or exclude interactions between particular Lagrangian surfaces and particular Eulerian surfaces. The Eulerian surfaces are created by default for each Eulerian material instance in the model; the Eulerian materials appear in the second column of the Edit Included Pairs and Edit Excluded Pairs dialog boxes, as shown in Figure 10–1. You can also include or exclude contact between two Lagrangian surfaces, but you cannot include or exclude contact between two Eulerian materials.

In addition to including or excluding Eulerian contact surfaces, you can specify unique contact properties between particular Lagrangian surfaces and particular Eulerian material instances. The Eulerian material instances are listed in the Edit Individual Contact Property Assignments dialog box. You cannot specify contact properties between two Eulerian material instances.
