can anybody make 2d shell tutorial?

The problem with doing a video tutorial of said case, is that most of the work would take place in Eficas, since the wizard in Salomé-MECA deals with 3D structures and the pressure load. A video is not suited to convey this.

Creating the geometry and mesh is very basic and contained in several video tutorials, so a written tutorial is a better way of describing the addition of using shells - I think Kees has a pretty decent one on the wiki.

Apparently between the Code Aster versions 9.x and 10.x the syntax became stricter. Assuming you use Aster 10.x, the CREA_MAILLAGE command generates an error because no TRIA6 elements are available in mesh. So comment out this part and the calculation runs. Well, on my computer it does.
[code:1]
meshmod=CREA_MAILLAGE(MAILLAGE=meshinit,
MODI_MAILLE=(_F(TOUT='OUI',
OPTION='QUAD8_9',),),);
#_F(TOUT='OUI',
# OPTION='TRIA6_7',),),); #### doesnot work anymore in ASTER10.X
[/code:1]

And indeed, the error message is a bit strange, reporting QUAD8 elements not available in stead of TRIA6 elements.

Wiki has been updated: www.caelinux.org/wiki/index.php/Contrib:...outers/platedynamics . But maybe other shells example experience the same problem. So, if you experience any further problems with the examples, please report them here. We will try to help.

Hoi Bridge,

Maybe it is easier to start a new example in the wiki for shell. All my examples are just what I needed at that moment in time: I wrote them down as they were. Sometimes a bit chaotic, ie not always one nicely separated issue, I know.
So I can start a new one with just the basics: geometry, boundary conditions, loads, mechanical properties, static calculation and extraction of displacements and stresses. Or you can make you own wiki. I am glad to participate and give advice.
If you have geometry and comm files, we can just start. So please
indicate what you prefer and see what we can make out of it.

One question about your geometry: I guess to need an extra line between P6 and P8?

Have a nice weekend.
