+
+Parameters to be defined in this mode:
+<ul>
+  <li><b>Groups (faces or volumes) </b> (<em>mandatory</em>): list of mesh
+    groups. These groups should be disjoint, i.e. should not have shared
+    elements.</li>
+  <li> If <b>Create joint elements</b> option is activated, flat
+    elements are created on the duplicated nodes: a triangular facet
+    shared by two volumes of two groups generates a flat prism, a
+    quadrangular facet generates a flat hexahedron. 
+    Correspondingly 2D joint elements (null area faces) are generated
+    where edges are shared by two faces.
+    <br>
+    The created flat volumes (or faces) are stored in groups. These groups are named
+    according to the position of the group in the list of groups: group
+    "j_n_p" is a group of flat elements that are built between the group \#n
+    and the group \#p in the group list. All flat elements are gathered
+    into the group named "joints3D" (correspondingly "joints2D"). The flat elements of multiple
+    junctions between the simple junction are stored in a group named
+    "jointsMultiples".</li>
+  <li> If <b>On all boundaries</b> option is activated, the volumes (or faces),
+    which are not included into <b>Groups</b> input, are considered
+    as another group and thus the nodes on the boundary
+    between <b>Groups</b> and the remaining mesh are also
+    duplicated.</li>
