Default 3D wing + wingtip meshing in ICEM

Hi everyone,

I need to create a structured mesh around a wing with a wingtip. I then plan to solve the flow with SUČ.

I'm completely new to ICEM so I based my 3D blocking on the 2D blocking from this vid : https://www.youtube.com/watch?v=EknKVAJGEJ8.

I have imported my geometry from CATIA and designed the farfield box in ICEM.

I have then created a 3D blocking (and splitted some blocks) and associated as many vertices and edges to geometrical entites as I could. Then I associated the block faces to geometrical surfaces. However, when I compute the premesh, things go wrong. Moreover, some parts (like the wing) are not meshed.
Another feature that sometimes fails is the split edge > automatic linear method to match the block edges to the airfoil curves.

I have attached the project so you can see by yourslves. Can someone give some hints on how to create my mesh properly?

Many thanks in advance,


Adrien

Hi, I have also generate mesh for wing naca0012 with wingtip. It is not easy, especially near TE.

The problem is that the association is not done well and wing blocking is not deleted. Here attached the revised one. It is not perfect, only better.
