I want to read the geometry information from a XDMF-file using dolfinx.
with dolfin it’s possible to read it using mesh.coordinates() and mesh.cells(),
but it doesn’t work in dolfinx because
'Mesh' object has no attribute 'cells'
so how can I read the endpoint coordinates of the cells in mesh with dolfinx?
with mesh.geometry.x in dolfinx I can read all the point of mesh, but how can I know then, which point belongs to one cell?
