Global refinement and L2 projection

Hello,

I would like to globally refine a given mesh several times, In fenics I implemented this by using refine(mesh) but it does not work in fenicsx. Is there another function or I need to use another way (markers etc.).
Is an L2 projection available between a mesh and its refinement?

Thank you in advance!

For refinement and transfering of meshtags, see: dolfinx/test_refinement.py at 621d1479adf1e1a8beb9eed86cc8ad3de963f223 · FEniCS/dolfinx · GitHub

We do not support assembly between different meshes, but there is a branch supporting interpolation between meshes, see:
