The mesh file is too big, even when zipped to place upload.

Hi Jean,

Apologies for not getting back to you.

The mesh seems to be ok, except for a few really skew elements.

Attached the zip file.

Thanks,
Chad

Thanks for the help Jean Pierre, I really appreciate it.

I think I've made progress but I came across a new error. From what I understand in the message file there is an encoding file missing in the Code_Aster directory.

>>> 2019/08/08-03:54:05.707  [local_shell@/home/chad/salome_meca/V2017.0.2/tools/Code_aster_frontend-20170/lib/python2.7/site-packages/asrun/system.py:333]
    ERROR : iret = 34304
    +++ STANDARD OUTPUT:
    Fatal Python error: Py_Initialize: Unable to get the locale encoding
    ModuleNotFoundError: No module named 'encodings'
   
I'd really appreciate your advice on this

Thanks a lot - the message file really helps a lot and I found the error.

The problem is a 3D one - I incorrectly selected 2D elements instead of 3D.

Now I'm getting an error saying this:

<S> Exception utilisateur levee mais pas interceptee.        !
   ! Les bases sont fermees.                                      !
   ! Type de l'exception : error                                  !
   !                                                              !
   !  le GROUP_MA  volume  ne fait pas partie du maillage :  mesh

I created a group of the elements in geometry and then created a volume group in mesh too. Which I then created in the model:
mesh = MODI_MAILLAGE(
  MAILLAGE=mesh,
  ORIE_PEAU_3D=(_F(
      GROUP_MA=('outer', )
    ), _F(
      GROUP_MA=('volume', )
    ))
)

So I don't understand why the error is occurring. I'd appreciate a little more help on this

My goal is to perform a linear static analysis on a piece of tubing. The tubing flattens out at the end, to form a valve - air is supposed to flow one way but be prevented from flowing back. Therefore the valve flattens completely at the end if the pressure outside the tube is greater than inside, ensuring that it is sealed.

Therefore we can assume the pressure inside the tube is constant at around 1500 Pa below the atmospheric pressure acting on the outside of the tube. The pressure difference between the inside and outside is supposed to cause the end of the pipe (flattened end) to deflect. I want to determine this deflection and nothing else.

I set the code up and tried to run it but it showed the <S> error. The 'RunCase_1' circle is orange and I understand this means the error isn't that serious? I am relatively new to Code_Aster so I am not sure what I have done wrong, I'd really appreciate getting some guidance on this.

I have attached a zip file of the command file, log file and RunCase_1.
