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.
Hello, do you solve this problem? I also have met the same difficulty.
Sorry it is not coded today in freefem, but you are well come to do.
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.
