4. Examples

The following examples illustrate the calculation of an acceleration spectrum, as well as the calculation of the displacement envelope:

TAB = MACR_SPECTRE (

MAILLAGE = MAIL,

PLANCHER = _F (NOM = “SOMMET”, GROUP_NO = (“GTOP1”,),),

NOM_CHAM = “ACCE”,

CALCUL = “ABSOLU”,

AMOR_SPEC = L_ AMOR_S,

FREQ = L_ FREQ,

NORME = 9.81,

RESU =( _F (RESU_GENE = RESUGENE,),),

)

TAB2 = MACR_SPECTRE (

MAILLAGE = MA1,

PLANCHER = (

_F (NOM = “NIV1”, GROUP_NO = (”N4_ NIV1 “, “N4_”, “N5_ NIV1 “, “N6_ NIV1”, “N7_ NIV1 “,),),

_F (NOM = “NIV8”, GROUP_NO = (”N4_ NIV8 “, “N4_”, “N5_ NIV8 “, “N6_ NIV8”, “N7_ NIV8 “,),),

),

NOM_CHAM = “DEPL”,

CALCUL = “RELATIF”,

LIST_INST = LISTE,

RESU =(

_F (RESU_GENE = TRAN_GE1,),

_F (RESU_GENE = TRAN_GE2,),

_F (RESU_GENE = TRAN_GE3,),

),

),

TAB3 = MACR_SPECTRE (

MAILLAGE = MA1,

PLANCHER = (

_F (NOM = “NIV1”, GROUP_NO = (”N4_ NIV1 “,),),

_F (NOM = “NIV8”, GROUP_NO = (”N4_ NIV8 “, “N5_ NIV8”,),),

),

NOM_CHAM = “ACCE”,

CALCUL = “ABSOLU”,

AMOR_SPEC = L_ AMOR_S,

LIST_FREQ = L_ FREQ,

RESU =( _F (RESULTAT = DYNAT_K1,),

_F (RESULTAT = DYNAT_K2,),

_F (RESULTAT = DYNAT_K3,),),

IMPRESSION =_F (FORMAT =” TABLEAU “, UNITE = 16,),

)

We can also refer to test case SDNV112A for another example of use.
