Hi,
I am trying to create a annular cyclinder mesh using blockmesh similar to mesh shown below (Its hollow inbetween. Flow occurs only in the annular section) I started with a simple cyclinder and tried deleting the central block/assigning the inbetween plane as wall/etc.... but nothing worked. Please let me know if it is possible to create such a mesh through blockMesh or should i create a geometry and snap it.. Any help/hint would be of great use!!! Thank you very much Regards, Ananthakrishnan |

Hello Ananthakrishnan,
Yes, it is possible to do what you want with blockMesh. It may exist more than one possible approach but I have done something similar following the steps bellow:
Maybe it's not the most straightforward approach, but it worked for me in the past. Hope it helps, Alex
