!CONTACTPAIR

Definition of contact surface pair used for contact analysis

1st Line

!CONTACT PAIR, NAME=<name> [,optional parameter]
Parameter
NAME Contact pair name (mandatory)
TYPE Type (omissible)
Parameter Name Parameter Value Contents
TYPE NODE-SURF Slave surface is the node group
Master surface is the surface group (default)
SURF-SURF Both the slave surface and master surface are the surface group

2nd Line or later

(2nd Line or later) SLAVE_GRP, MASTER_GRP
(Hereinafter the same)
Parameter Name Attributions Contents
SLAVE_GRP C Slave surface node / surface group name
MASTER_GRP C Surface group name of the master surface

Note:

  • When using mesh-refinement functionality, always use "TYPE=SURF-SURF".
  • Even when "TYPE=SURF-SURF" is used, the internal contact algorithm within FrontISTR is one for point-to-surface type contact.

Reference

  • When "TYPE=SURF-SURF" is used, the contact pair is converted to a node-surface type contact pair within FrontISTR by automatically generating a node-group from the slave surface-group.
  • The group-name of the automatically generated node group is concatenation of "FSTR_S2N_" and the group-name of the original slave surface-group.
