jacopo gave more information on the question:
I have To use yade for this project And compare its result with others taken
with others software. My aircraft have to crash on a soil with 18 m/S velocity.
IT should penetrate The soil around 1/2 meters with the "nose". I would like
to see on video the deformations of the aircraft( if something break, like The
wings And etc.), that S why i would like To have facet facet contacts. Or, if
Is The same, clumping The structure. What do you suggest) . Thanks for the
clear about gts -facets. However i don t have To register the deformation , But
i would like To see that the aircraft Is taking "damage" during the impact

Jan Stránský requested more information:
Hello,
> do i have To clump the facets creating a rigid body? Becouse now i don
t know if they will stay togheter during the impact .
if you use TranslationEngine, the motion of all facets is prescribed.
They stay together, but they won't react on the contact with soil. From
this point of view, probably using a clump is a better option.
> do i have to reconvert My file.txt in a file.gts?
no, in both ways you just get facets..
> the aircraft Will act a rigid body. I would like To see the aircraft
deformations
I think this is most difficult part of your question. Please describe more the
experiment (how much is the aircraft crashed etc.)
Currently I feel Yade might not be the right software to use..
> And register the forces acting on the aircraft center of gravity.
this is no problem
> I know the facet-facet contact doeSn t exist. How can i do?
You could implement it, but why do you need facet-facet contact? For
modeling aircraft deformations?
cheers
Jan
