 Abbreviated names RBC Orders $$k=1$$ Reference elements dual polygon Number of DOFs dual polygon(n): $$n$$ Mapping covariant Piola continuity Components tandential to facets are continuous Notes These elements are defined on the barycentric dual grid. These elements are defined as a linear combination of Nédélec first kind basis functions on the fine grid. Categories Vector-valued elements, H(curl) conforming elements
