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 = MAPOU,

AFFE =_F (TOUT =” OUI “, PHENOMENE =” MECANIQUE “,

MODELISATION =” TUYAU_3M “, ,) **,

)

Assignment of characteristics:

  • Pipe radius and thickness

  • Sector number and layer number

CARA = AFFE_CARA_ELEM (

MODELE = MODELE,

POUTRE =_F (GROUP_MA =( “POUTRE “, “ POUTRE0”), **

SECTION =” CERCLE “, CARA =( “R”, “EP”), VALE =( 10.0,1.0 )) **,

TUYAU_NSEC = 4, TUYAU_NCOU = 2, ),

)

3.3. Tested values and results#

All sub-point coordinates for the 2 pipes are tested.
