3. Operands

3.1. Operand BASE

♦ BASE = low

A concept of the mode_meca type that contains the vectors defining the projection subspace.

3.2. Operand NUME_DDL_GENE

♦ NUME_DDL_GENE = nu_gene

Generalized numbering based on BA.

3.3. Operands FREQ_EXTR/INST_EXTR

♦/FREQ_EXTR = freq

/INST_EXTR = inst

Actual value of the extraction parameter of the ground impedance matrix. It is either a frequency (keyword FREQ_EXTR) for complex impedances calculated by CALC_MISS option TYPE_RESU =” FICHIER “, or an instant (keyword INST_EXTR) for changes in temporal impedance obtained by the Laplace method by CALC_MISS option TYPE_RESU =” FICHIER_TEMPS”.

3.4. Operand UNITE_RESU_IMPE

UNITE_RESU_IMPE = uresimp

The logical unit of the ground impedance matrix calculated by CALC_MISS option TYPE_RESU =” FICHIER “or option TYPE_RESU =” FICHIER_TEMPS”.

This matrix can either already be calculated and given as an entry in the study profile, or the result of CALC_MISS in the same command file.

3.5. Operand ISSF

♦ ISSF =/'NON',/'OUI',

If “OUI”, consideration of the format specific to studies by MISS3D in soil-structure-fluid interaction in accordance with this same keyword in CALC_MISS.

3.6. Operand SYME

♦ SYME =/'OUI',

If present, allows the terms of the impedance matrix read to be symmetrized.

3.7. Operand TYPE

◊ TYPE =/'BINAIRE'

/”ASCII” [DEFAUT]

This operand makes it possible to read the impedances calculated by the CALC_MISS command in a binary format file if necessary.
