Mesh of Circular Cylinder fluid flow.
 

I am trying to look at the fluid flow around a circular cylinder in a rectangular flow domain and are having trouble creating my mesh. I want to create a refined quadrilateral mesh.
could anyone help?

Could you tell us explicitly? the geometry that you have modelled is circular one or rectangular?

I have attached a copy of my mesh so far. I have modeled my circular cylinder within the rectangular flow domain.

Thanks for you help!
