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 ',

))))

))))
