Here is the install script for fenicsx linked from #701
fyi @ivanmaione this will overwrite fencis-ufl everything else could be installed side by side
The labelling of the mesh in dolfinx seems to pull over the same information as our gmsh importer and test_override_lcar_surf
but test_mesh_poly
fails and gives the same result instead of half the node number but if I double lcars for the second half I get the expected result... @ivanmaione @oliverfunk :

Accomplished in #2872 will go into develop with the python3.10 upgrade
Description of issue / requirement to address
At some point in the future we need to move to fenicsX as fenics is unmaintained and had its last update in 2019
Proposed solution
Update to fenicsX https://fenicsproject.org
Alternative solutions
N/A
