Procedure IMPR_MISS_3D
1 Goal
To write on a file the data input for a seismic study with MISS 3D.
The data transmitted by the procedure IMPR_MISS_3D are:
·
the contribution of the loads intern with a superstructure in the form of a second member
projected on a modal basis made up of clean or constrained modes,
·
signals of harmonic excitation or transient associated with these loads,
·
signals of seismic excitation,
·
parameters of calculation of the harmonic or transitory evolution.
The ground or the fluid is modelled by code MISS 3D and the superstructures by Code_Aster which
provides for them a dynamic macronutrient printed on the file of interface by
IMPR_MACR_ELEM [U7.04.33] with the format “MISS_3D”.
The call to this procedure is répétable. With each call an evolution calculated corresponds by
MISS 3D whose launching is ensured by MACRO_MISS_3D [U7.03.11].

3 Operands
3.1 Operands
MACR_ELEM_DYNA
MACR_ELEM_DYNA = macro_dyna
Name of the concept macr_elem_dyna produces by projection on the basis of modal clean mode
and static modes of a superstructure modelled by Code_Aster.
3.2 Word
key
EXCIT
/
EXCIT
Key word factor defining the loads intern with this structure. Can be repeated for
to summon several loads associated with different signals.
3.2.1 Operand
VECT_ASSE
VECT_ASSE = vecas
Vector assembled correspondent with a loading applied to this structure (concept of the type
cham_no_DEPL_R).
3.2.2 Operands
FONC_MULT/COEF_MULT
Allow respectively to define the signal or the multiplying coefficient of the definite loading
in key word EXCIT.
/FONC_MULT = fonc
Evolution defined point by point by a concept of the function type having for parameter
frequency F or time T according to the type (harmonic or transitory) of the dynamic evolution
calculated by MISS 3D.
/COEF_MULT = coeff
Multiplying coefficient of the loading independent of the loading.
3.3 Word
key
EXCIT_SOL
/
EXCIT_SOL
Key word factor defining the loads resulting from the ground, given by their direction, their type and it
signal in associated time or frequency. Can be repeated to summon several loads resulting from
ground. It is compatible with key word EXCIT to combine in the same evolution calculated by
MISS 3D of the loads applied directly to the structure or resulting from the ground.
3.3.1 Operand
DIRECTION
DIRECTION = (d1, d2, d3)
Components of the vector direction of load, renormé to 1., according to which one recombines the effects
of an incidental wave P vertical with those of transverse waves SV and HS.
