Hi all,

I'm new user and I'm meshing a tank with the blockMesh tool.

Since I want to generate concentric cylinders inside the tank, I have created different cylinders, but due this apporoach the mesh overlap.

Does anybody know which could be the best strategy to avoid this issue?

Thanks,

Fabio


My blockmeshDict file:

FoamFile
{
version 2.0;
format ascii;

root "";
case "";
instance "";
local "";

class dictionary;
object blockMeshDict;
}
