Iterate on cells and get cell properties in dolfinx

dolfinx

Hi everyone,
In the old fenics I could easily iterate over cells and get the specific properties of each cell:

import fenics

mesh = fenics.UnitSquareMesh(2, 2)

for cell in fenics.cells(mesh):
    cell_volume = cell.volume()
    midpoint = cell.midpoint()
    inradius = cell.inradius()

Is there a way to do something similar in dolfinx?

As legacy fenics only supported simplices (some limited support for quadrilaterals and higher order non affine geometries) all these operations were well defined.

Many of these functions are no longer trivial to obtain

Midpoints can be Gotten with
