C     In the case where two elements are connected through
C     a Lagrangian face (or edge), that is to say that all nodes of
C     the shared edge are Lagrangian, there is no exchange in terms
C     of convection between this two elements : the face, or edge, has to 
C     be considered as a (moving) sliding wall.
C     Hence, the neighbors in IVOIS are set to zero for corresponding faces, or edges.
