 320 =================================
 321
 322 Double nodes on shared faces between groups of volumes and create flat elements on demand.
 323
 324 The list of groups must contain at least two groups. The groups have to be disjoint: no common element into two different groups.
 325
 326 The nodes of the internal faces at the boundaries of the groups are doubled. Optionally, the internal faces are replaced by flat elements.
 327
 328 Triangles are transformed into prisms, and quadrangles into hexahedrons.
 329
 330 The flat elements are stored in groups of volumes.
 331
 332 These groups are named according to the position of the group in the list:
 333 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.
 334 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.
 335 All the flat elements are gathered into the group named "joints3D" (or "joints2D" in 2D situation).
 336 The flat element of the multiple junctions between the simple junction are stored in a group named "jointsMultiples".
 337
 338 This example represents an iron cable (a thin cylinder) in a concrete bloc (a big cylinder).
 339 The big cylinder is defined by two geometric volumes.

 347 Here, the 4 groups of volumes [Solid_1_1, Solid_2_1, Solid_3_1, Solid_4_1] constitute a partition of the mesh.
 348 The flat elements on group boundaries and on faces are built with the
 349 2 last lines of the code above.
 350
 351 If the last argument (Boolean) in DoubleNodesOnGroupBoundaries is set to 1,
 352 the flat elements are built, otherwise, there is only a duplication of the nodes.
 353
 354 To observe flat element groups, save the resulting mesh on a MED file and reload it.
