Hello,

I am solving a electromagnetic numerical problem. I can construct the 3d Nedelec finite element with degree 1 (Edge03d) and the system matrix K. What I want to know is how the matrix K is been constructed in this case, especially how to assemble such global matrices.

I can find the paper discussing higher-order Nedelec element online, which is HIGH ORDER EDGE ELEMENTS ON SIMPLICIAL MESHES. Is there any good reference that FreeFEM++ implements for the Nedelec element of degree 1?

Regards
