Extended analysis of SSNP155

Hi,

The analysis of SSNP155 has been successful, and I are trying to analyze by adding one object based on SSNP155.
I changed it referring to the SSNP155 comm file , but an error occurred and I cannot solve it.
Can anyone give me a hint?
The error is as follows:

------------------------------------------   
   !  les 18 mailles imprimées ci-dessus n'appartiennent pas au modèle et pourtant elles ont été affectées dans le mot-clé facteur : !
   ! FORCE_CONTOUR                                                                                                                   !
------------------------------------------   
Convert to english

the 18 meshes printed above do not belong to the model and yet they were affected in the key word factor:!
FORCE_CONTOUR
------------------------------------------   

The same message can be obtained by changing FORCE_CONTOUR to FORCE_COQUE, FORCE_ARETE, FORCE_INTERNE, and FORCE_FACE.

Re: Extended analysis of SSNP155

Hello.

This error message happends when there is no FE element defined in the model.
For your "load" group try to define fake 3D elements and use Force_Arrete (I think that goes with 3D element edges)
Than you will have some 3D elements without stiffness but CA will be able to distribute your load between the nodes.
For me that trick usually works.

Otherwise there is no SSNP155 in my CA but if you share it I will try to show what I mean.

Re: Extended analysis of SSNP155

Thank you for response. I try it, but I had no idea how to operate it.
Could you please tell me the procedure, etc.?
I attach the necessary files below :

*.step : parts of Geometry
ssnp155a_2017.comm : without clasp, Minimal changes from SSNP155
C_p2s1d2.med : without clasp
ssnp155a_2017cl.comm : with clasp no fake 3D
C_p2s1d2c2.med : with clasp no fake 3D
ssnp155a.38 : to be read
astk.png : astk example
r021124_salome.pdf : mesh example

code_aster ver. : STA13.6(CAELinux2018, salome_meca 2018.0_LGPL)

Re: Extended analysis of SSNP155

Hi. The problem with the model was a bit more than what you mentioned. It was just the first one in the line.
I almost managed to make it work. The calculation starts but stops due to singularity, the 3rd (new) part has to be supported somehow.
Unfortunately I am going to move during the weekend and have no time to play around with supports and contacts for the 3rd part.
But you can try it and share if it works.

You were missing finite elements and material assigned to the elements for the clasp
Also time history for the new load.

Now the clasp needs to be supported somehow better than what I tried smile

Re: Extended analysis of SSNP155

Thank you for your efforts in this problems.
As you said, I tried to fix the comm file, but I had a problem.
ASTK cannot read your med file.
I attached a file of The error message when loading with Salome_meca 2018.0_LGPL .
Could you please reattach med file after you move ?
Sorry to trouble you.

I'm very happy to find a solution when I read your post.
Thank you very much !!
