# VUINTERACTION

 User subroutine to define the contact interaction between surfaces with the general contact algorithm. User subroutine VUINTERACTION: can be used to define the mechanical and thermal interaction between contact surfaces; must provide the entire definition of the interaction between the contact surfaces; can utilize a user-specified tracking thickness to determine potential points of interaction on a surface (and thus which nodes should be passed into the subroutine); can use and update solution-dependent state variables for node-to-face contact and node-to-analytical rigid surface contact; and must be used with the general contact algorithm. The following topics are discussed:
