How to make an O-type 2D mesh
 
1 Attachment(s)
Hello Everyone, I'm new to Ansys and I'm trying to reproduce the enclosed mesh
(Source:Transition on a flat plate with a semi-circular leading edge under uniform and positive shear free-stream flow A. Palikaras, K. Yakinthos, A. Goulas)

I don't understand how to obtain that kind of curvature while maintaining the rectangular outer walls.
I tried to split the domain with 2 lines in the direction of the diagonals and then sizing, but the result isn't quite the same.
Thank everyone in advance for a response
