I'm currently working on meshing a 3 dimensionnal wing with a rounded wing-tip. I try to make a structured mesh but there is a problem meshing the trailing edge. Since it is a sharp trailing edge (NACA4418) I can't mesh it in a structured way. Does anyone have some advice to help me mesh my wing tip ? That could be very helpful.

Thanks for the answer !!

You can try using a C-type grid by cutting along the trailing edge and specifying the points on the wake of the wing. Also you can try creating H-grids like they use in Turbomachinery.

I would use an H-grid. Off-set one of the vertex at the trailing edge to the top of the wing. Then use an O-grid from the wing tip to the far field to capture the irregular shape and improve grid quality.
