5. Assignment of values#

Two methods can be used to assign characteristic values:

  • the classical method: operand whose name evokes the characteristic treated followed by a value or a list of values. Examples:

COQUE = _F (EPAIS = 1.E-2, GROUP_MA = “G1”),

COQUE = _F (ANGL_REP = (0., 90.), GROUP_MA = “G2”),

  • for assignments concerning BARRE, POUTRE, and DISCRET, as well as ORIENTATION for beam elements and discrete elements, the large number of characteristics that could be affected led to a better adapted syntax:

CARA = (…) # list of feature names

VALE = (…) # list of values corresponding to the characteristics

An example is given below to illustrate this case.

_F (SECTION =” CERCLE “, CARA =(” R “,” EP “), VALE =( 0.09,0.01), GROUP_MA =” M6 “),

_F (SECTION =” CERCLE “, CARA =(” R1 “,” R2 “), VALE =( 0.1,0.2), GROUP_MA =(” M2 “,” M4 “)),

_F (SECTION =” CERCLE “, CARA =(” EP1 “,” EP2 “), VALE =( 0.02,0.05), GROUP_MA =(” M2 “,” M4 “)),

),

It is possible to use the functionalities of the Python language. The example below retrieves quantities calculated by the MACR_CARA_POUTRE command and then assigns them. Using python requires putting PAR_LOT =” NON “in the DEBUT command.

PRE_GIBI ()

SECTION = MACR_CARA_POUTRE (NOEUD = “N1”, GROUP_MA_BORD = “BORD”)

ii = 2

alpha0 = SECTION [“ALPHA”, ii]

cdgx0 = SECTION [“CDG_X”, ii]

cdgy0 = SECTION [“CDG_Y”, ii]

AIRE0 = SECTION [“AIRE”, ii]

IY0 = SECTION [“IY_PRIN_G”, ii]

IZ0 = SECTION [“IZ_PRIN_G”, ii]

EY0 = SECTION [“EY”, ii]

EZ0 = SECTION [“EZ”, ii]

JX0 = SECTION [“CT”, ii]

JG0 = SECTION [“JG”, ii]

AY0 = SECTION [“AY”, ii]

AZ0 = SECTION [“AZ”, ii]

IYR20 = SECTION [“IYR2_PRIN_G”, ii]

IZR20 = SECTION [“IZR2_PRIN_G”, ii]

carelem= AFFE_CARA_ELEM (MODELE =mod,

POUTRE = (

_F (GROUP_MA =( “POUT1”, “POUT2”), SECTION =” GENERALE “,

CARA = (“A”, “Y”, “IZ”, “IZ”, “IZ”, “AY”, “AZ”, “EY”, “EZ”, “JX”, “JG”, “JG”, “IYR2”, “”, “”, “IZR2”),

VALE = (AIRE0, IY0, IZ0, AY0,, AZ0,, EY0, EZ0,, JX0, 1889,,,,,,,,,,,, JG0,,,, IYR20 IZR20

If the mesh section contains a surface mesh group named “square”, it is possible to use the table from macr_cara_beam directly in the following way:

SECTION = MACR_CARA_POUTRE (MAILLAGE =mail, NOEUD = “N1”, GROUP_MA_BORD = “BORD”)

carelem= AFFE_CARA_ELEM (MODELE =mod,

POUTRE = (

_F (GROUP_MA =( “POUT1”, “POUT2”), SECTION =” GENERALE “,

TABLE_CARA = SECTION, NOM_SEC =” CARRE “,
