Mapped Mesh (square cells) for a Comoposite Geomety

I am trying to make a mapped mesh for a composite geometry, the geometry is as follows, a square and an ellipse with an angle of -45 degrees at the center of the square. I want all the mesh cells to be squares in the square and in the ellipse.
I am getting error 4012:Domain must be bounded by one connected edge component only.
I was thinking of finding some kind of mathematical relationship to characterize the ellipse inside the square as a contrast in electrical conductivity from scalar expressions.
Any one could help on this?

I also encountered the same mesh error. Have you figured out the problem? Why such an error is produced?

Well I suppose its because it's not obvious to achieve the "quadrature du cercle"
The quad mesh generator have some limitations on the topology of the domains.
Why not use triangles ? with the high order shape functions (second order by default) COMSOL goes far with "tri/thets"s, also where other older FEM used far higher "order elements"

Good luck
