 ==== 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.

OOFEM will automatically find finite elements overlapping with those hanging nodes. This is facilitated through SpatialLocalizerInterface in particular implementation in OOFEM's elements.
-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.
+One way in Salome is creating two independent meshes for concrete and reinforcement. A compound mesh can join both meshes - just be careful not to tick "Merge coincident nodes and elements". Continue with export to unv and process with unv2oofem.py. Reinforcement is normally represented by OOFEM's truss elements. Reinforcement nodes need to be grouped in "OOFEM-Hanging*" group at the end of ctrl file, e.g.
