3D Airfoil with Sharp Trailing Edge - Mesh Help

Toofanian · August 8, 2016, 19:28

Hi all,

I am using the ANSYS Workbench 16.2 meshing application to mesh a 3D flow domain for use in Fluent.

When I add inflation layers to my mesh, they produce highly skewed cells around the trailing edge of the airfoils, since they come to a sharp point. How can I resolve this? I have seen some solutions posted, but none for this software.

Screencap of current mesh attempt:

Thanks,
Toofanian

Hi Toofanian(nice name),

It would not be too bad a trade-off to switch to ICEM block structured meshing if you're still facing the issue with your mesh. C-grid is a best practice for airfoils

Best.
