Hi guys, simple question: How can I create a 2D mesh where each element is a square and not a triangle ? Thanks!!

There is very limited support for quadrilateral elements in dolfin. However, this support has been extended in dolfinx , see Defining FunctionSpace over a Quadrature Element in dolfinx

I would not use dolfin-xml, as it is not suited for parallel computing. I suggest using: Converter from GMSH to XDMF (with physical groups)
