Hi,

A couple of questions on simple geometries, to better explain here, for use in a more complex model for CFX.

1. For a hollow cylinder how can the hex elements be biased so that they are clustered at the inner and outer circumferences? The 1st image shows a simple mesh with the Sweep Method and then I put on a Mapped Face (2nd image) which gave the structured radial distribution. But how can the elements be biased? I cannot find any option to do so.

2. For a filled cylinder how can those perfect ICEM type O-grids with boundary layer bunching be made? I tied the MultiZone method (3rd image) and then put on a Face Sizing (last image) but cannot find the options to make those ICEM style O-grids.

Thanks.

I guess these things are not possible (yet?) in ANSYS Meshing?

Ludvik is on a distinguished road
With base tools in ANSYS Meshing not. But you may open ICEM CFD directly into AM (Multizone, Write ICEM CFD Files > Interactive) and create this mesh. After build grid will be automatically loaded into AM environment.
