The operation to delete contact entities is the same as for Entity Deletion. Before deleting a Contact entity, dependencies of that contact must be considered. For example, a force might be used as one of the arguments of a Function Expression or User Subroutine. If a simulation error occurs after deleting a Contact entity, its dependency must be checked. When a Faceset, Patchset or Edgeset is deleted, the dependent Contact entity will be deleted simultaneously.
