[ICEM] Sharp trailing edge Hexa mesh

Dinu · October 6, 2022, 10:57

Hello everyone,
I'm trying to make a simple hexa mesh for a sharp trailing edge wing. I have created a c grid and set the appropriate values. However, I get two edges (right next to the wing tip trailing edge) with very bad quality hexas. Trailng edge with bad elements.png

If the BLk and Tin files are needed please let me know how i can contact you and I will be happy to send it, I get a error when i try to upload the zip file here.

Thank you in advance!

If you have not already watched them, then I recommend you (and most other ICEM CFD Users) watch this 3-part YouTube series by ANSYS:

Can the mods update the ANSYS Meshing & Geometry wiki/FAQs with these three videos by ANSYS (PSYMN).

You need to transform the block in the wing and adjacent span-wise to Y-block. unfortunately ,in my experience you cannot use the O-Grid with Y-block method.
