I progress... but not so quick I want!! 
In the zip : .comm, .mess and .med of my problem!
I try to put my earth building wall between a wood structure... I try to use LIAISON_MAIL to do that...
I obtain a lot of that :
and an exception JEVEUX... Calculus broken!
Any Ideas?
Thanks by advance!

UPDATE !!!!!
Something wrong I've found in my other files...
but every-time I found new bug, every-time a new one appear!
I think it came by LIAISON_MAIL in my DDL... but how can I define my contacts??
VPoteauG and VPoteauD (Right and Left) are master on the wall (Faces : McoteD and McoteG) and master on the poutre (PoBas)!
MVol (wall) is master on the poutre (Face : PoBas)

That's what I think too... 
But in the list of nodes... there only 3 Nodes !
I think there are more nodes over-constrained!
Anyway, how can I do to annihilate this nodes?
My basis is ENCASTRE : it's my ground (bedrock)...
The two columns are ENCASTRE in bedrock and master over the wall and the beam.
The beam is esclave for columns and wall.
The wall is master for the beam, and esclave for the columns!

Simple: you just don't include them in the LIAISON_MAIL group 
Create the group as usual, then edit the group and remove the nodes. I can't view the mesh atm., but that's what you need to do.
