Satish Perivilli Guest Posts: n/a	Hi I am trying to work on a cylindrical volume inside a brick volume. I want these to remain as two volumes. 1. Can anyone tell me how to get an O-grid inside the cylinder and a structured mesh outside?? 2. If there is an annulus inside a brick, how do I do the same?? 3. Is there a way to model the cylindrical volume in polar coordinates and use Cartesian system outside?? Please let me know Thanks
