Converting legacy FEniCS code to FEniCSx causes issue

Good evening
I wish I was able to answer your question, but I have another one instead.

In the code above you use

Ue = VectorElement("CG", domain.ufl_cell(), 1, dim=3)

it looks like ufl.VectorElement has been replaced with basix.ufl.element)

So I tried the following with your simple beam mesh

# Define the vector element using basix
Ue = basix.ufl.element(
    family=basix.ElementFamily.P,  # Lagrange family
    cell=basix.CellType.interval,  # 1D cell type
    degree=1, 
    shape=(3,))

but I get this error I don’t manage :

---> 13 W = FunctionSpace(domain, Ue*Ue)
unsupported operand type(s) for *: '_BlockedElement' and '_BlockedElement'

Also tried :

Ue = dolfinx.fem.functionspace(domain, ("CG", 2,(gdim,)))
W = FunctionSpace(domain, Ue*Ue)

but got :

----> 2 W = FunctionSpace(domain, Ue*Ue)
TypeError: unsupported operand type(s) for *: 'FunctionSpace' and 'FunctionSpace'

Can anyone help me through this one ?
