Operands ========= Operand RESU_GENE ------------------ ♦ RESU_GENE = TG .. csv-table:: "/", "concept of the tran_gene type containing generalized vectors such as displacement, speed and acceleration for various times. If the results come from the extrapolation of measurement results on a numerical model (command PROJ_MESU_MODAL), the generalized vectors are of the displacement, deformation and stress types. In this case, the recombination base is of the mode_meca type." "", "" "/", "concept of the mode_gene type containing the generalized vectors of the modes calculated following a projection on a modal basis." "", "" "/", "concept of the type harm_gene containing the generalized displacement, speed and acceleration vectors of the harmonic response of a structure calculated after a projection on a modal basis" Operand MODE_MECA ------------------ .. code-block:: text ◊ MODE_MECA = fashion A concept of the mode_meca type containing a base of natural modes 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 the command REST_SOUS_STRUC [:external:ref:`U4.63.32 `]. It is therefore a double reproduction, after having made a double projection (cf. example in [:ref:`§4 <§4>`]). Operand NUME_DDL ----------------- .. code-block:: text ◊ NUME_DDL = number 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 rendering on the ddls 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 reduced model (see test case SDNV107A for example). Operands TOUT_ORDRE/NUME_ORDRE/NUME_MODE/TOUT_INST//LIST_INST/INST -------------------------------------------------------- .. code-block:: text ◊/TOUT_ORDRE = 'OUI' To reproduce the mode_gene concept on all modes. .. code-block:: text /NUME_ORDRE = num List of integers containing the order numbers of the modes on which the restoration is performed. .. code-block:: text /NUME_MODE = num List of integers containing the numbers of the modes in the global spectrum on which the reproduction takes place. .. code-block:: text /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. Operands FREQ/LIST_FREQ -------------------------- These operands are used in the case of a reproduction on the physical basis of generalized harmonic calculations (harm_gene). .. code-block:: text /FREQ = freq Frequency at which we want to restore the harmonic calculation .. code-block:: text /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. Operands TOUT_CHAM/NOM_CHAM ------------------------------ .. code-block:: text ◊/TOUT_CHAM = 'OUI' Allows you to restore the symbolic name fields DEPL, VITE and ACCE contained in the generalized result (tran_gene, harm_gene). .. code-block:: text /NOM_CHAM = nomcha List of the symbolic field names you want to return: 'DEPL', 'VITE', '', 'ACCE' and possibly if they have been calculated, 'ACCE_ABSOLU', 'EFGE_ELNO', 'SIPO_ELNO', '', '', ',' SIGM_ELNO 'or' FORC_NODA '. Restitution of the fields' EFGE_ELNO ',' SIPO_ELNO ',' ',' ',' ',' SIGM_ELNO 'and' FORC_NODA 'is possible in multi-taps. Operand INTERPOL ----------------- .. code-block:: text ◊ INTERPOL = .. csv-table:: "'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 [:external:ref:`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." Operands PRECISION/CRITERE ----------------------------- .. code-block:: text ◊ PRECISION = prec .. code-block:: text ◊ CRITERE = When INTERPOL is equal to 'NON' indicates with what precision the search for the moment to be restored must be done .. csv-table:: "'ABSOLU':", "search interval [Inst - prec, Inst +prec]," "'RELATIF':", "search interval [:ref:`(1 - prec).Inst, (1 + prec) .Inst <(1 - prec).Inst, (1 + prec) .Inst>`] Instantiating the moment of return." Operand MULT_APPUI ------------------- After the transitory calculation of the generalized seismic response of a structure, the user must indicate 'OUI' under the keyword MULT_APPUI to restore the absolute movements (and/or speeds and/or accelerations). If he does not specify anything, the operator returns the relative quantities. **Note:** If the transitory calculation of the generalized seismic response of a structure is done in option TRAN_GENE of CALC_MISS *,* the result is directly absolute without specifying MULT_APPUI =' OUI ', because the load comes directly from the seismic ground forces calculated by MISS. Operands ACCE_MONO_APPUI and DIRECTION -------------------------------------- .. code-block:: text ◊ | ACCE_MONO_SUPPORT = (gamma1, gamma2, gamma3), [function] | DIRECTION = (dx1, dy1, dz1, dz1, dx2, dy2, dz2, dx3, dy3, dz3), [l_R] After calculating the generalized seismic response of a monounced structure, the user indicates the name of the imposed accelerograms (keyword ACCE_MONO_APPUI) **and** the directions of the earthquake (keyword DIRECTION) to restore the absolute accelerations (accelerations only, which will be stored in field ACCE_ABSOLU). If he does not specify anything, the operator returns the relative quantities. Field ACCE_ABSOLU will then be absent. **Note:** It is possible to impose up to 3 *accelerogram* s *sub* the keyword ACCE_MONO_APPUI\ *.* They*must* come *must* be the*them* them*imposed* s*s*under the keyword*FONC_MULT*d*under the keyword* *d* a keyword factor EXCIT of *e the command* DYNA_VIBRA *.* If the transitory calculation of the generalized seismic response of a structure is done in option TRAN_GENE of CALC_MISS *,* the result is directly absolute without specifying ACCE_MONO_APPUI and DIRECTION, because the load comes directly from the seismic ground forces calculated by MISS. Operand CORR_STAT ------------------ After the transitory calculation of the generalized seismic response of a structure, provided that the user has requested 'CORR_STAT' =' OUI 'in DYNA_VIBRA, he can then restore the displacements (and/or speeds and/or accelerations) with correction by the static modes of the truncation of the modal base. The user must specify 'OUI' under the CORR_STAT keyword. If he does not specify anything, the operator returns the quantities without static correction. Operand GROUP_NO ----------------- .. code-block:: text ◊/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 node/mesh groups corresponding to the places where the user wants to render kinematic fields. Operand TITRE -------------- .. code-block:: text ◊ TITRE = title Title attached to the concept produced by this operator [:external:ref:`U4.03.01 `].
