Finite element shape function sets with a unique + * relation from shape function number to vector @ref GlossComponent + * "component". What this means is that each shape function of a + * vector-valued element has exactly one-nonzero component if an + * element is primitive. This includes, in particular, all scalar + * elements as well as vector-valued elements assembled via the + * FESystem class from other primitive (for example scalar) elements + * as shown in @ref step_8 "step-8", @ref step_29 "step_29" or @ref + * step_22 "step-22". On the other hand, the FE_RaviartThomas and + * FE_Nedelec classes provide non-primitive finite elements because + * there each vector-value shape function may have several non-zero + * components.
