!CONTACT

Definition of contact conditions

Parameter

GRPID       = Boundary conditions group ID
INTERACTION = SSLID (Infinitesimal slip contact, Default) / FSLID (Finite slip contact) / TIED (Tied)
NTOL        = Contact normal direction convergence threshold (Default: 1.e-5)
TTOL        = Contact tangential direction convergence threshold (Default: 1.e-3)
NPENALTY    = Contact normal direction Penalty (Default: stiffness matrix 1.e3)
TPENALTY    = Contact tangential direction Penalty (Default: 1.e3)
CONTACTPARAM = Contact scan parameter set name（specified by `!CONTACT_PARAM, NAME`）

2nd line or later

Using INTERACTION = SSLID, FSLID

(2nd line) PAIR_NAME, fcoef, factor

Parameter Name	Attributions	Contents
PAIR_NAME	C	Contact pair name (Defined in !CONTACT PAIR)
fcoef	R	Friction coefficient (Default: 0.0)
factor	R	Friction penalty stiffness

Using INTERACTION = TIED

(2nd line) PAIR_NAME

Parameter Name	Attributions	Contents
PAIR_NAME	C	Contact pair name (Defined in !CONTACT PAIR)

Example of Use

!CONTACT_ALGO, TYPE=SLAGRANGE
!CONTACT, GRPID=1, INTERACTION=FSLID
CP1, 0.1, 1.0e+5

Note

• if CONTACTPARAM is specified, the destination !CONTACT_PARAM must be defined prior to the !CONTACT card. If this parameter is omitted, the default contact scan parameter set is used.
