3. Modeling A

3.1. Characteristics of the mesh

The pipe mesh is composed of a SEG3 type mesh.

3.2. Characteristics of modeling

Model definition:

MODELE = AFFE_MODELE (

MAILLAGE = MAIL,

AFFE =_F (GROUP_MA =” TUBE “, PHENOMENE =” MECANIQUE “,

MODELISATION =” TUYAU_3M “, ,) **,

)

Assignment of characteristics:

• Radius and thickness of the pipe

• Sector number and layer number

CARA = AFFE_CARA_ELEM (

MODELE = MODELE,

POUTRE =_F (GROUP_MA =( “TUBE “, )) **,

SECTION =” CERCLE “, CARA =( “R”, “EP”), VALE =( 0.5, 0.2), 0.2),

TUYAU_NSEC = 8, TUYAU_NCOU = 3, ), ),

)

3.3. Tested values and results

All values assigned to the sub-points are tested.

An extraction is performed at a particular point using a POST_CHAMP and recorded in a table using CREA_TABLE. The value of all components is tested including the coordinates.
