[blockMesh] Grid generation cross flow over circular cylinder -- CFD Online Discussion Forums

July 7, 2010, 09:02	Grid generation cross flow over circular cylinder	#1
Yanma New Member Join Date: Jul 2010 Posts: 3 Rep Power: 16	Hi everyone, i just started to familiarize myself with OpenFoam. I want to simulate cross flow over a circular cylinder for relatively low Re numbers (100-300). I was thinking about using a block structured mesh consisting of 3 blocks. An O-type mesh in the region of the cylinder wall, a C-type mesh for the region in front of the cylinder and the wake region, and a coarse mesh for the rest of the flow field. What do you think of this grid structure? Are you proposing another grid structure? Has anyone got an example of a blockMeshDict file for a similar problem? Many thanks in advance.
