SALOME supports elements of second order, without a central node
-(quadratic triangle, quadrangle, tetrahedron, hexahedron, pentahedron
-and pyramid) and with central nodes (bi-quadratic triangle and

Quadratic mesh can be obtained in two ways:
- Using a global \ref quadratic_mesh_anchor "Quadratic Mesh"
hypothesis. (Elements with the central node are not generated in this way).
