[SOLVED] hey need help with a 2D beam problm .comm was created by Mihir
Hey! as I'm new here, i was trying to get started with a simple 2D beam fixed at both ends and having a uniformly distributed load. So I created the geometry and mesh using Salome-Meca , and then generated the .comm file using Eficas . I noticed in the .comm file that the AFFE_CARA_ELEM icon is in yellow, while all the rest are in green (i get a feeling that something's not right here-so I've attached the source file of the .comm file at the end).
When i try to run the Aster file later, it does not do the computation; it comes up with a message the command file is not in use.
Kindly tell me where I'm going wrong as I've been going through tutorials and web content for the past 2 days, and I really cant proceed any further without help.
Thanking in advance.

Code_Aster release : STA11.4 on OpenSUSE 12.3 64 bits - EDF/Intel version
Replied by Claus on topic Re: hey need help with a 2D beam problm .comm file
What version of Code_Aster are you using? A yellow icon indicates that you're missing a field in the CALC_ELEM group. I must admit that I can't remember the requirements in my head right now, but compare to a working .comm file.

Please post your .comm file - don't copy/paste it, but upload the file

Hoi D_Riel
I havenot used beams in 2D, but you may need to add a wall thickness.
In 3D I use:
Beam1=AFFE_CARA_ELEM(MODELE=BeamMod,
POUTRE=(_F(GROUP_MA='beam1',
SECTION='RECTANGLE',
CARA=('HY','HZ','EP',),
VALE=(0.0200,0.0100,0.0025,),),),
ORIENTATION=(_F(GROUP_MA='beam1',
CARA='VECT_Y',
VALE=(0.0,0.0,1.0,),),),)
u4.42.01.pdf says:
|'H'|'EP',
or
|‘HY’|'HZ'|'EPY'|'EPZ'
