<h2>Double nodes on groups boundaries</h2>
|
||||
|
||||
\n Double nodes on shared faces between groups of volumes and create flat elements on demand.
|
||||
\n The list of groups must describe a partition of the mesh volumes. The nodes of the internal
|
||||
faces at the boundaries of the groups are doubled. Optionally, the internal faces are replaced
|
||||
\n The list of groups must contain at least two groups. The groups have to be disjoint: no common element into two different groups.
|
||||
\n The nodes of the internal faces at the boundaries of the groups are doubled. Optionally, the internal faces are replaced
|
||||
by flat elements.
|
||||
\n Triangles are transformed into prisms, and quadrangles into hexahedrons.
|
||||
\n 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".
|
||||
|
||||
\n
|
||||
\n This example represents an iron cable (a thin cylinder) in a concrete bloc (a big cylinder).
