Is Q1 element possible in fenics?

1

Hi,

I need to do compute on a simple square domain but with square cells and Q1 element.
I read the tutorials on buildin meshes such as RectangleMesh, but it generates triangle cells and most examples works with P elements. Is square cells possible in fenics?

Regards
Juntao
