Simple 3d model beam was created by Torben
Hello. I am trying to build a simple 3d beam model with Salomé (3.2.9) and Code_Aster (9.02). I keep getting errors like:

!
!
! <EXCEPTION> <MODELISA7_76> !
! !
! !
! le noeud Node_1 ne fait pas partie du maillage : BeamMesh !
! !
! !
! !
! !
!
!

I tried with and without named group for elements. When checking the mesh (MED) in Salomé everything is fine but when the study is executed I get this error. The basic systems work when testing them with some of the tutorials from CAElinux.

My Code_Aster commands are:

DEBUT();
BeamMesh=LIRE_MAILLAGE(UNITE=20,
FORMAT='MED',
NOM_MED='Mesh_1',
INFO_MED=2,);
BeamMod=AFFE_MODELE(MAILLAGE=BeamMesh,
AFFE=_F(GROUP_MA='Edge_1',
PHENOMENE='MECANIQUE',
MODELISATION='POU_D_T',),);
ElemData=AFFE_CARA_ELEM(MODELE=BeamMod,
POUTRE=_F(GROUP_MA='Edge_1',
SECTION='RECTANGLE',
CARA='H',
VALE=0.010,),);
Steel=DEFI_MATERIAU(ELAS=_F(E=2.1e11,
NU=.28,),);
BeamMat=AFFE_MATERIAU(MAILLAGE=BeamMesh,
AFFE=_F(TOUT='OUI',
MATER=Steel,),);
BndCnd=AFFE_CHAR_MECA(MODELE=BeamMod,
DDL_IMPO=_F(NOEUD='Node_1',
DX=0.,
DY=0.,
DZ=0.,
DRX=0.,
DRY=0.,
DRZ=0.,),);
BeamSolu=MECA_STATIQUE(MODELE=BeamMod,
CHAM_MATER=BeamMat,
CARA_ELEM=ElemData,
EXCIT=_F(CHARGE=BndCnd,
TYPE_CHARGE='FIXE',),);
FIN(FORMAT_HDF='OUI',);


I attach the message file which has all the Code_Aster commands and the output for tracing.

I will appreciate your feedback.<br /><br />Post edited by: Torben, at: 2009/04/15 03:44

Ja, verden er lille :lol: Thanks for answering.

I initially assigned the NOEUD directly with a node number (integer). That did not work. Then I defined the labed in the mesh but I of course should have changed reference to GROUP_NO='Node_1'. Now the error disappeared. Thank you very much.
