Hello, I am studying high order FEMs for Maxwell problems. And I want to use BDM1 face element in 3D, I hope FreeFEM++ can include this element.

What’s a good current ref on the issues? I wan into this [1] as a first google hit.  
II’m mostly intersted in learning this stuff right now looking for questions  
rather than answers 🙂 The citation below is from 2009 not sure if it captures  
the state of the art then or now but it mentions FreeFem . Thanks.
