Can I define a DG (P1) space on triangle mesh with dofs defined on middle points of the edges?

Now, I know how to define a DG space

mesh = RectangleMesh(10, 10, 1, 1)
V = FunctionSpace(mesh, 'DG', 1)

The DOFs of V are defined on vertex.
Can I define another space with the DOFs of V defined on the middle points of the edges?

You can get this with ``` FunctionSpace(mesh, BrokenElement(FiniteElement("CR", triangle, 1))) ```

@colinjcotter Thanks for your quick reply.
I tried it and found the right syntax should be

V = FunctionSpace(mesh, BrokenElement(FiniteElement('CR', triangle, 1)))

Yes, I forgot FiniteElement, sorry! On 12 Mar 2022, at 16:03, Yang Zongze ***@***.***> wrote:  @colinjcotter<https://github.com/colinjcotter> Thanks for your quick reply.

I think I can mark this as the answer. Thanks!
