3. Operands

3.1. Cyclic substructuring (keyword factor CYCLIQUE)

3.1.1. Operand MODE_CYCL

♦ MODE_CYCL = mocy

Mode_cycl concept resulting from a cyclic substructuring calculation.

3.1.2. Operand MAILLAGE/NB_SECTEUR

♦ MAILLAGE = email

The mesh_sdaster concept used to define the skeleton. It is accompanied by the keyword NB_SECTEUR, an integer that gives the number of repetitions of this mesh to obtain the complete structure of the skeleton.

3.1.3. Keyword SECTEUR

♦ SECTEUR

Keyword factor for creating a skeleton from a mode_cycl result produced by MODE_ITER_CYCL [U4.52.05]. Allows you to define on the base sector the list of visualization meshes that will be repeated cyclically.

3.1.3.1. Operands TOUT/GROUP_MA

◊/TOUT

All the meshes of the base sector mesh will be visualization meshes.

◊/GROUP_MA = GRMA

List of visualization mesh groups for the base sector.

3.2. Classic substructuring

3.2.1. Operand MODELE_GENE

♦ MODELE_GENE = average

Name of the concept modele_gene from DEFI_MODELE_GENE [U4.65.02] defining the global structure on which we want to define the skeleton.

3.2.2. Keyword SOUS_STRUC

♦ SOUS_STRUC

Key word factor for creating a skeleton following a calculation by classical dynamic substructuring.

Allows you to define the list of visualization meshes on each substructure of the generalized model.

3.2.2.1. Operand NOM

◊ NOM = structure_name

Name of the substructure. It must be the same as one of the names of the substructures that define the generalized model (see DEFI_MODELE_GENE [U4.65.02]).

3.2.2.2. Operands TOUT/GROUP_MA

◊/TOUT

All the cells in the substructure mesh will be visualization meshes.

◊/GROUP_MA = GRMA

List of substructure visualization mesh groups.

3.3. Tags SQUELETTE and RECO_GLOBAL

The keyword SQUELETTE defines an initial concept of skeleton type where we will merge the nodes of the interfaces by the keyword RECO_GLOBAL, either all these nodes (TOUT = “OUI”), or selectively a group of nodes grno1 (operand GROUP_NO_1) from the substructure name_sstru1 (operand SOUS_STRUC_1) with a group of nodes grno2 (operand GROUP_NO_2) from the sub-structure nom_sstru1 (operand) with a group of nodes grno2 (operand) of the sub-structure structure name_sstru2 (operand SOUS_STRUC_2).

These substructures must belong to the modele_gene type concept specified by the MODELE_GENE operand.

The skeleton modified by the fusion will be the result of the DEFI_SQUELETTE operator.

3.3.1. Operands DIST_REFE/CRITERE/PRECISION

The fusion will take place according to a proximity criterion that is either absolute (in relation to dist_ref) or relative (in relation to dist_ref*prec).

3.4. Keyword NOM_GROUP_MA

In the case where an initial concept of skeleton type (entered by the keyword SQUELETTE) is modified by merging the nodes of the interfaces (using the keyword RECO_GLOBAL), it is then possible to recover groups of cells (entered by the operand GROUP_MA) in the substructure nomsst (entered by the operand SOUS_STRUC) by assigning them a new name for a group of elements (operand NOM) in the result skeleton.

3.5. Keyword EXCLUSIF

In the case of a classical substructuring calculation, only. By putting EXCLUSIF =” OUI “, we remove the groups of cells from the initial meshes in the final skeleton.
