+<b>Propagation of Node Distribution on Opposite Edges</b> allows to propagate
+distribution of nodes onto an opposite edge. If a local hypothesis and
+propagation are defined on an edge of a quadrangular face, the
+opposite edge will have the same number of nodes and the same
+relations between segment lengths, unless another hypothesis
+has been locally defined on the opposite edge.

\note A mesh shown in the 3D Viewer can prevent selection of faces
and edges, just hide the mesh to avoid this. To avoid a long wait when a
geometry with many faces (or edges) is displayed, the number of faces
(edges) shown at a time is limited by the value of "Sub-shapes
preview chunk size" preference (in Preferences/Mesh/General tab).<br>
- Whatever shapes are specified by this
- parameter, the element layers are not constructed on geometrical
- faces shared by several solids in 3D case and edges shared by
- several faces in 2D case. In other words the element layers can be
- constructed on boundary faces and edges, and are not constructed on
- internal faces and edges. There is an exception to this rule in 2D
- case: if "Viscous Layers 2D" hypothesis is assigned to a sub-mesh,
- the element layers can be constructed on boundary edges of the shape
- of this sub-mesh.
+ If faces/edges without layers are specified, the element layers are
