Create a contact prevention constraint

This example shows how to improve surface wrap geometry using contact prevention constraints.

In the Simulation Navigator , under the surface wrap recipe node, right-click the Constraints node and choose New Contact Prevention Constraint.

Select the two polygon entities that should not be in contact.

Set the following:

• Sizing Option = Relative Refinement

• Local Subdivision = 3

• Level = High

• Click OK.

In the Simulation Navigator , right-click the surface wrap recipe node and choose Update.

You can now add two additional contact prevention constraints to create gaps between the cube and the cylinder and between the cube and the sphere.
