4. Operand OPERATION = “SUPERPOSE”

With the “SUPERPOSE” choice, all entities (meshes, nodes, mesh groups, and node groups) from both meshes are retained. The only problem to be resolved concerns the name of these entities (possible name conflict because the two meshes may contain, for example, nodes with the same name).

To solve these potential name problems:

1. Knots and stitches are still renowned. This means that the user cannot know the names of the nodes and meshes in the result mesh. In general, it will have to use (which is always recommended) the names of mesh groups and groups of nodes. Or he will have to print the mesh to know the names chosen.

2. The names of node groups and mesh groups are retained as much as possible. If two mesh groups (or two node groups) have the same name in both meshes, the group coming from the 2nd mesh is renamed automatically and the name change is indicated in the message file.
