Ignore Contact Law

Description

This contact law is not actually a contact law. Its effect on problem that have contact are different when modeling material contact then when modeling crack contact.

Material Contact

For multimaterial contact, this law ignores multimaterial mode thereby reverting to a single velocity field or revert to state as if there was no material interface. 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, and therefore always "stick" at their interfaces.

Crack Contact

When modeling explicit cracks, this law ignores crack contact. As a result, this law will give poor results for crack problems unless those cracks never experience contact.

Properties

This contact law has no properties that need to be set.
