Description
This frictional contact law is not actually a contact law. This law ignores contact on explicit crack surfaces. For multimaterial contact, this law will revert to a single velocity field or revert to state as if there was no material interface.
This law will give poor results for cracks that are in contact, unless those cracks never experience contact. For multimaterial mode simulations, this mode reverts to a single velocity field. For simulations with more than two materials where some contact by other contact laws and others should use single velocity fields, the better approach than using this law is to use the shareMatField (matID) in materials that should share the same field.
Properties
The law has no properties that need to be set.
