Konrad,
I don't think we have that element. It is in general not terribly
difficult to implement new elements, in particular for lowest order
ones. The interface of finite element classes is quite self-contained,
and you don't need to know anything about the rest of the library to
understand it. There are also plenty of examples to start from, and we'd
be happy to help with questions you may have!
Best
W.
