Hello All,

Can anyone please throw some light on how to generate Cylindrical blockMesh.

Actually I need this kind of cylnidrical shape mesh for SnappyHexMesh.

I am snapping Mixing chamber and for that if the Back Ground mesh is cylindrical then it can give much better results compared to Block shape BlockMesh.

Thanks

Yes I have already gone through it.. but I have one more problem.

I am not able to run this cylinderMesh.m4 file even after following the procedures written there.

this is very complicated one.
can i have it as a simple blockmeshDict file ?

Hello,

I don't know why, but there is something missing after the m4 to blockMesh conversion. The syntax FoamFile is missing in the BlockMeshDict. If you add it at the beginning, it should work.

At first, you run the
Code:
 m4 cylinderMesh.m4 > blockMeshDict
from the folder where your cylinderMesh file is. Then you open the created blockMesh File and add before the header "version..." at the beginning
Code:
 FoamFile
{ version ...
  .... MeshDict;
}
and copy the file in your constant/polyMesh folder and then it should work.

Hope this helps,
Mike
