Hi everyone,

I am having trouble trying to refine the mesh near the walls of a duct using snappyHexMesh. My case is a simple empty straight duct. But I need to get the mesh near all four walls to be about 4 times smaller than those in the centre in both y and z directions. I am not sure if the snappyHexMeshDic file that I modified is correct because when I ran it, the mesh created by blockMesh don't seem to change at all when I open paraview. There was no error though. Can someone help?

Regards,
Charles
