Mesh around a rotating cylinder
1 Attachment(s)
:confused:Hello guys!!
I am a new CFX user and I have been working in a air flow over a rotating cylinder simulation. I know that in this type of simulation, the boundary layier is really relevant. So, because of this, I have been workin really hard trying to improve my mesh around the cylinder. I found one interesting paper about this type of simulation that shows the attached picture. The picture shows the mesh I'm trying to do. But, i have lots of difficult to implement that. I would like to know if somebody can help me to do that mesh ( not exactly that ond..but close). Can somebody tell me the steps I should follow to create such mesh? I am using the workbench and I will simulate in CFX. I have created a thin plate with a small hole (cylinder) in the middle. So now, how should I proceed?

I have no idea about the AM, but can be easily done in ICEM. tin and blocking files are also attached with post for cylinder of 1 dia.

This might be required method you are looking for in AM and DM

Right, if you want a mesh with this sort of topology, ICEM CFD is easier. But you could still do it in ANSYS Meshing... Just subdivide the plate into each of those regions and map each face... But I don't recomend that...

If I were doing this in AMP for CFX, I would just use the sweep mesher (or the multizone mesher). It will use a more unstructured mesh on the surface and sweep it thru the thickness of the plate... That type of mesh can actually be more efficient in some cases because the unstructured mesh can transition to larger sizes...

Thanks for the answer guys! I'm going to try the advices!
