3. Operands

3.1. Operands RESU_GENE/RESULTAT

/RESU_GENE = TG

/	concept of the tran_gene type containing, for various times, generalized vectors such as displacement, speed and acceleration of the transient response calculated by substructuring.
/	concept of the mode_cycle type containing the generalized vectors of the modes calculated by cyclic substructuring.
/	concept of the mode_gene type containing the generalized vectors of the modes calculated by dynamic substructuring.
/	concept of the type harm_gene containing the generalized displacement, speed and acceleration vectors of the harmonic response of a structure calculated by substructuring.

/RESULTAT

This keyword can be used when first returning a result resulting from a calculation by dynamic substructuring on a first skeleton (visualization mesh). An enriched skeleton is then defined in which the nodes at the interfaces of the substructures have been merged and all or some of the groups of nodes or cells from the initial mesh have been merged. The result keyword then corresponds to the reproduction of a mode_meca, dyna_trans, evol_noli concept on a new enriched skeleton (cf. example in [§4]).

3.2. Operand MODE_MECA

◊ MODE_MECA = fashion

A concept of the mode_meca type containing a base of eigenmodes obtained by dynamic substructuring.

This operand is used in the case of a reproduction in the physical system of a result of a transitory calculation performed on a modal basis calculated by dynamic substructuring. The modal base contained in the mode_meca concept was obtained by a previous REST_SOUS_STRUC.

In this case, you must enter the same retrieval medium (keyword SQUELETTE or SOUS - STRUC) used to restore the modal base.

3.3. Operand NUME_DDL

◊ NUME_DDL = number

A concept of the nume_ddl type containing a numbering corresponding to a reduced model in the case of a calculation with dynamic condensation when the user wants a summary of the degrees of freedom belonging to this reduced model.

This operand thus makes it possible to obtain, following the retrieval, a mode_meca concept that could be used later for a calculation on the model.

3.4. Operands TOUT_ORDRE/NUME_ORDRE/TOUT_INST/LIST_INST/INST

◊/TOUT_ORDRE = 'OUI'

To restore on all the modes of the mode_cycl or mode_gene concept.

/NUME_ORDRE = num

List of integers containing the numbers of the modes on which the restoration is performed.

/NUME_MODE = num

List of integers containing the numbers of the modes in the global spectrum on which the reproduction takes place.

/TOUT_INST = “OUI”

If you want to reproduce all the moments contained in the generalized result (tran_gene).

/LIST_INST = list

List of increasing real values of the listr8 type containing the moments for which you want to perform the restoration.

/INST = inst

List of real numbers containing the moments on which the restoration takes place.

For a transitory calculation, we check that the moments requested by option LIST_INST are in the domain of definition of the tran_gene.

The results at any instant can be obtained by linear interpolation between the results of two computing moments actually contained by the tran_gene.

3.5. Operands FREQ/LIST_FREQ

These operands are used in the case of a reproduction of generalized harmonic calculations (harm_gene).

/FREQ = freq

Frequency at which we want to restore the harmonic calculation

/LIST_FREQ = list

List of reals containing the frequencies for which you want to perform the reproduction.

For each frequency indicated, the fields obtained are restored at the nearest calculation frequency. There is no interpolation.

3.6. Operands TOUT_CHAM/NOM_CHAM

◊/TOUT_CHAM = 'OUI'

Allows you to restore the symbolic name fields DEPL, VITE and ACCE contained in the generalized result (tran_gene, harm_gene).

/NOM_CHAM = nomcha

List of the symbolic field names that we want to return: “DEPL”, “VITE”, “ACCE”.

3.7. Operand INTERPOL

◊ INTERPOL =

“LIN”:	an interpolation is authorized between two moments; this interpolation is only usable between two moments of calculation, but can lead to errors if the two archiving moments [U4.53.21] are separated by a very long time compared to the periods of the phenomena studied.
“NON”:	the return must be made strictly speaking.

3.8. Operands PRECISION/CRITERE

◊ PRECISION = prec

◊ CRITERE =

When INTERPOL is equal to “NON” indicates with what precision the search for the moment to be restored must be done

“ABSOLU”: “RELATIF”:

search interval [Inst - prec, Inst +prec], search interval [(1 - prec).Inst, (1 + prec) .Inst] Instantiating the moment of return.

3.9. Operand SECTEUR

◊/SECTEUR

Sector number of the cyclic structure on which the result (of the mode_cycl type) will be returned to the physical system under cyclic substructure.

3.10. Operand SQUELETTE

/SQUELETTE

Name of the skeleton mesh of the global structure on which the result will be rendered: see operator DEFI_SQUELETTE [U4.24.01].

3.11. Operand SOUS_STRUC

/SOUS_STRUC = structure_name

Name of the substructure on which the result will be returned: see operator DEFI_MODELE_GENE [U4.65.02].

3.12. Operand GROUP_NO

◊/GROUP_NO = lgrno

/GROUP_MA = lgrma

After a transient dynamics calculation on a modal basis, the user can restore kinematic fields on only a portion of the nodes or meshes of the mesh.

List of groups of nodes/meshes corresponding to the places where the user wants to render kinematic fields.

3.13. Operand CYCLIQUE

◊ CYCLIQUE = _F (

◊ NB_SECTEUR = ns [I] ◊ NUME_DIAMETRE = nl [I]

◊ RESULTAT2 = res [evol_elas]

[evol_noli]

[dyna_trans]

[evol_char]

[meca_mode] )

The DEFI_SQUELETTE [U4.24.01] operator makes it possible to regenerate the complete mesh of a cyclic symmetric structure from the mesh of a sector of this structure.

The option CYCLIQUE in REST_SOUS_STRUC makes it possible to restore on this new skeleton mesh the fields at the nodes calculated on the model of the sector alone and taking into account cyclic symmetry (with LIAISON_MAIL or LIAISON_CYCL for example).

The action of this REST_SOUS_STRUC option consists of:

1/ in the static case (only one field at the node provided) to rotate this field to the nodes on the skeleton mesh

2/ in the dynamic case (2 fields at the nodes provided RESULTAT and RESULTAT2) to combine the fields at the nodes and make them rotate on the new mesh.

3.14. Operand TITRE

◊ TITRE = title

Title attached to the concept produced by this operator [U4.03.01].
