Use this blockMeshDict to automatically create a structured mesh for cylinder given the radius, height and average cellSize for the final mesh. There will be 3 boundary patches for you in the final mesh: inlet, outlet, and cylinerWall. You also have the option to make the inner square curvy-like by setting the innerArc to yes.
radius 0.05; height 0.6; cellSize 0.003; innerArc yes; // yes/no
