 303 =================================
 304
 305 Double nodes on shared faces between groups of volumes and create flat elements on demand.
 306
 307 The list of groups must contain at least two groups. The groups have to be disjoint: no common element into two different groups.
 308
 309 The nodes of the internal faces at the boundaries of the groups are doubled. Optionally, the internal faces are replaced by flat elements.
 310
 311 Triangles are transformed into prisms, and quadrangles into hexahedrons.
 312
 313 The flat elements are stored in groups of volumes.
 314
 315 These groups are named according to the position of the group in the list:
 316 the group j_n_p is the group of the flat elements that are built between the group \#n and the group \#p in the list.
 317 If there is no shared faces between the group \#n and the group \#p in the list, the group j_n_p is not created.
 318 All the flat elements are gathered into the group named "joints3D" (or "joints2D" in 2D situation).
 319 The flat element of the multiple junctions between the simple junction are stored in a group named "jointsMultiples".
 320
 321 This example represents an iron cable (a thin cylinder) in a concrete block (a big cylinder).
 322 The big cylinder is defined by two geometric volumes.

 329 Here, the 4 groups of volumes [Solid_1_1, Solid_2_1, Solid_3_1, Solid_4_1] constitute a partition of the mesh.
 330 The flat elements on group boundaries and on faces are built with the
 331 2 last lines of the code above.
 332
 333 If the last argument (Boolean) in DoubleNodesOnGroupBoundaries is set to 1,
 334 the flat elements are built, otherwise, there is only a duplication of the nodes.
 335
 336 To observe flat element groups, save the resulting mesh on a MED file and reload it.
