 ==== Extension for sets ====
 Boundary conditions and material assignments can be handled via sets. Salome needs to define groups on which those sets will operate.

+==== Extension for hanging nodes ====
+Hanging nodes are nodes located on finite elements. They do not add degrees of freedom but use element interpolation functions instead. For example, reinforcement can be attached to concrete elements using hanging nodes. Any group of nodes in Salome represent hanging nodes when its name starts with "OOFEM-Hanging". OOFEM will automatically find finite elements overlapping with those hanging nodes.
+One way in Salome is creating two independent meshes for concrete and reinforcement. Reinforcement is finally represented by OOFEM's Truss elements, mesh nodes need to be grouped in "OOFEM-Hanging*" group. A compound mesh can join both meshes, exported to unv and processed with unv2oofem.py.
