TUYAU Elements

Hi.
I have some issues with TUYAU_6M elements. I am still getting this error:
   !----------------------------------------------------------------------------------------------!

   !   * Peut-être avez-vous oublié de renseigner le mot clé CARA_ELEM dans la commande courante. !
   !   * Dans la commande AFFE_CARA_ELEM, avez-vous affecté des caractéristiques d'"orientation"  !
   !     sur la maille incriminée ?                                                               !
   !----------------------------------------------------------------------------------------------!
Can you help me out? I am enclosign comm and other files.
Do you think it might be caused by geometry? I have one edge with opposite direction then others.
Thank you.
Michal

Re: TUYAU Elements

Hello Patch,

have you solved your problem in the mean time? I just stumbled over the same error message. That would spare me searching...

Best regards,

Re: TUYAU Elements

hello

there is a late answer because I myself struggled about that problem.

You must make sure that all your 1D-elements used for the TUYAU have the right orientation: start point of the subsequent element must be the end point of the element before. This can automatically be adjusted with command 

MESH  = MODI_MAILLAGE(reuse =MESH, INFO=2,    MAILLAGE=MESH,
                      ORIE_LIGNE=(   _F(GROUP_MA='Wire_1',  GROUP_NO='P0_1', VECT_TANG=(1, 1,1 , ),),      ),)

Then everything runs ok. I attach .comm.

I myself have also a similar question: is it possible to model a  bifurcation with TUYAU elements, for example a T-junction?
