Hi,

In December 2023, the BDM2 elements were added as “tests”. I’m wondering if they are working as of today? I’m using a code that uses a slightly modified version of FreeFEM as base, and when I try to incorporate the FreeFEM implementation of BDM2 it doesn’t work.

I think, the finite element is repair, I will be ok, but very few test are done with this finite element, so but can exist.
