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.
