7. Specific objects for formulation CONTINUE

7.1. Item CARACF

(o) '. CONTACT. CARACF ': V R long = ZCMCF * NZOCO

 Object indexed by the contact area number.

2	Value of the increase coefficient in contact	COEF_CONT COEF_PENA_CONT	MMINFR	COEF_AUGM_CONT
3	Type of algorithm in contact (increased or penalized) 1 — STANDARD 3 — PENALISATION	ALGO_CONT	MMINFI	ALGO_CONT
4	Value of the coefficient of increase in friction	COEF_FROT COEF_PENA_FROT	MMINFR	COEF_AUGM_FROT
5	Type of algorithm in friction (increased or penalized) 1 — STANDARD 3 — PENALISATION	ALGO_FROT	MMINFI	ALGO_FROT
6	Coulomb coefficient of friction	COULOMB	MMINFR	COEF_COULOMB

12	Number of directions of friction excluded 0 — no direction excluded 1 — only one direction excluded 2 — all directions excluded	SANS_ *_EN DIRE_EXCL_FROT	MMINFI	EXCL_DIR

7.2. Objects PSANOFR/SANOFR

In formulation CONTINUE only, we treat the keywords SANS_GROUP_NO_FR/SANS_NOEUD_FR which make it possible to identify knots or particular meshes on contact surfaces:

(f) '. CONTACT. PSANOFR ': V I long = 1+ NZOCO

(f) '. CONTACT. SANOFR ': V I long = STOCNO

The storage of this information is substantially the same as the storage of the nodes excluded from contact (cf. § 5.4).

A utility routine allows you to tell if a node is part of the groups described above:

SUBROUTINE CFMMEX (DEFICO, TYPEXC, IZONE,, NUMNOE, SUPPOK)

IN DEFICO: SD POUR THE DEFINITION OF CONTACT

IN TYPEXC: TYPE FROM EXCLUSION

'FROT' DONNE PAR SANS_ *_EN

'CONT' DONNE PAR SANS_ *

IN IZONE: NUMERO OF THE ZONE OF CONTACT

IN NUMNOE: NUMERO ABSOLU FROM NOEUD TO CHERCHER

OUT SUPPOK: VAUT 1 IF THE NOEUD FAIT PARTIE DES NOEUDS EXCLUS

7.3. Item EXCLFR

(f) '. CONTACT. EXCLFR ': V R long = ZEXCL * NZOCO

This object is used to specify the friction direction exclusion vectors in the case of option SANS_ *_FR.

Object indexed by the contact area number.

Index on the area	Description	DEFI_CONTACT	Question MMINF*
1	Direction of exclusion following X	DIRE_EXCL_FROT	MMINFR	EXCL_FROT_DIRX
2	Direction of exclusion following Y	DIRE_EXCL_FROT	MMINFR	EXCL_FROT_DIRY
3	Direction of exclusion following Z	DIRE_EXCL_FROT	MMINFR	EXCL_FROT_DIRZ

7.4. SD ligrel

(o) '. CHME. LIGRE ': V sd_ligrel

This sd_ligrel SD (cf. [D4.06.02]) contains the definition of late Lagranges added to the model on the slave nodes by the continuous formulation.
