The script appli.sh uses python2 in some commands line 113 and 114. Debian does not have python2 anymore and thus I made an alias in my syestm for python2=python3 Still no luck. please help.

Hello, I am making a beam out of a thick panel screwed to a Steel stud (see image) And I am trying to figure out how often the screws should be placed attaching the panel to the steel stud. I am trying to study the shear between the two surfaces when the beam is loaded and starts bending. so I defined  half the contact surface as a geometry group "Contact" , Loaded the beam with transverse load and Calculated the stresses SIEF_NOEU

then did an integral over the stress field on the Contact patch to calculate the total shear force on the screws.

table = POST_ELEM(
  INTEGRALE=_F(
    GROUP_MA=('Contact', ),
    NOM_CHAM='SIEF_NOEU',
    NOM_CMP=('SIYZ', ),
    TYPE_MAILLE='2D'
  ),
  RESULTAT=reslin

Is this the correct approach into calculating that force?

Thanks in advance.

I am trying to learn to use CALC_FERRAILLAGE and made a simple beam with both ends fixed (3D modelization)  But I am failing miserably. Code aster reports an error that I have no idea how to interpret. I have tried many things but just can't get it to work. Here is an extract of my Mess file. Any ideas?

Hello I am trying to install Salome_meca version 2018.0.1 in a Debian 10 computer and it crashes with this error code:

The workaround published in another forum thread seems to work:

 LD_PRELOAD='/usr/$LIB/libstdc++.so.6' ./salome 

Any ideas how to fix this in a more permanent elegant way?

I am conducting a study of thermal flux through some boundary areas, but the Integrale command is not calculating the correct areas.

here is the output table I get:

Flux Energy                                                                 
NOM_CHAM         NUME_ORDRE   INST         VOL          GROUP_MA         INTE_FLUY    INTE_FLUX    MOYE_FLUY    MOYE_FLUX   
FLUX_NOEU                   0  0.00000E+00  1.65161E-01 Outside          -1.46523E+00  7.78683E-03 -8.87156E+00  4.71469E-02
FLUX_NOEU                   0  0.00000E+00  1.65161E-01 Inside           -1.46523E+00  7.78683E-03 -8.87156E+00  4.71469E-02
FLUX_NOEU                   0  0.00000E+00  1.65161E-01 Screwt           -1.46523E+00  7.78683E-03 -8.87156E+00  4.71469E-02

But the Real Areas of the surfaces as measured in the mesh module

  Outside---> 0.08252335
  Inside----> 0.08258048
  Screwt----->5.713349e-5

So why Am I getting 1.6516 E-1 which happens to be twice the area of the Inside surface!!! Also Inside = Outside + Screwt and they are all reported with the same 1.6516E-1

Any ideas?

I am attaching the comm file.

I was just wondering how to model a fastener as this guy did in here.

h ttps://youtu.be/VA0eg0LWfWM

I think You define your contact, master and slave surfaces, but then how do you set the fastener and its pre load.

Do we have anything like that in Code Aster?

just Curious

Regards.
