-
-Double nodes on groups boundaries
-=================================
-
-Double nodes on shared faces between groups of volumes and create flat elements on demand.
-
-The list of groups must contain at least two groups. The groups have to be disjoint: no common element into two different groups.
-
-The nodes of the internal faces at the boundaries of the groups are doubled. Optionally, the internal faces are replaced by flat elements.
-
-Triangles are transformed into prisms, and quadrangles into hexahedrons.
-
-The flat elements are stored in groups of volumes.
-
-These groups are named according to the position of the group in the list:
-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.
-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.
-All the flat elements are gathered into the group named "joints3D" (or "joints2D" in 2D situation).
-The flat element of the multiple junctions between the simple junction are stored in a group named "jointsMultiples".
-
-This example represents an iron cable (a thin cylinder) in a concrete block (a big cylinder).
-The big cylinder is defined by two geometric volumes.

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