Thank you, JLF! It's really very similar.

Hello, everyone!
I want to calculate a frame with cable, an example of which is given here.

Unfortunately, aster's code gives an error and I don't understand the reason for this. Please tell me how to fix this?

I changed it. Thank you!

Hello,

You must use GROUP_MA_BORD in MACR_CARA_POUTRE to compute all the characteristics of the cross section.
Cf  [U4.42.02] MACR_CARA_POUTRE, pg 4 and [U4.42.01] AFFE_CARA_ELEM key POUTRE/BEAM

JLF

Thank you! It has helped me. It need contour from line elements for GROUP_MA_BORD.

Can I visualize this section in a Paraview?

Hello, everyone! I want to attach Tshape section to beam-elements, but Code_Aster get me error. What's a problem?

Hi, cwf007! I'm not good specialist in frequency response in code_aster, but on this youtube channel got helpful information for this type analysis in Code_Aster.

Very nice. I will continue to understand the topic. Thanks again, Mario, for your links!

#10 Re: Code_Aster usage » Number of processors. » 2021-02-25 20:58:31

Thank you very much, Mario! I will deal with the information.
I also heard that you can turn on the number of cores through the ASTK module. Does this also work?

Hello! I new user in Code_Aster. I have a simple question. How can I change the number of processors involved in the calculation?
In Salome_Meca, I cannot change that.

#12 Re: Code_Aster usage » testcase .comm files » 2021-02-10 13:56:35

I find it here on my computer /salome_meca/V2019.0.3_universal/tools/Code_aster_stable-v144_smeca/share/aster/tests
This is very cool, I can view and work through various cases.

Hello, everyone! II am a new user in code_aster.
I can see a lot of testcase for Code_aster.
But often they didn't have instruction or .comm files for applications. Where can I find it?

Thanks a lot! The tensile was like example. I did not know that it is possible to combine meshes like this in Salome. This will help me a lot in further research! Thanks a lot again!

Hello everybody! Happy New Year!
I want to make glue contact of three bodies with different materials, but I can not imagine how to do it in Salome_Meca. Can anyone give me some logic? For example, a path will be three cubes following each other, one end is fixed, a tensile force is applied to the other. 
I can glue two bodies together. But three doesn't work.
Thank you!

Hello, dear colleagues! I am a new user and do not know many nuances. I want to set the load in the form of a uniform temperature on the body and see the deformations and stresses arising from this. I used operate
load0 = AFFE_CHAR_MECA(
  DDL_IMPO=_F(
    GROUP_NO=('temp', ),
    TEMP=10.0
  ),
  MODELE=model
)
and Code_Aster get me error.
   ! Erreur utilisateur :                                             !
   !   Vous voulez contraindre le ddl TEMP sur un ensemble de noeuds, !
   !   Mais ce ddl n'existe sur aucun de ces noeuds.                  !
How I understood it mean, what I used  wrong model (meca - 3D)
And I didn't find a reference temperature to set the temperature difference.
In this connection, I had a question: is there a simple way to set the temperature load in the Code_aster like in Ansys (I'm from this environment) or needs to define two related types of analysis: thermal and mechanical, and set a uniform temperature in the thermal analysis.
Thank you for your attention.
