I am trying to mesh a circle within a rectangle (or a cylinder inside of a rectangular prism in 3D) using blockMesh. I would like to mesh the circle using an O-grid method, which should then transition into a regular mesh in the rectangle around it. Could anybody provide any pointers on how to do this?

Many thanks!
