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 bloc (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.
