+ | ==== 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 " | ||
