[ICEM] 3D Airfoil

ExtraTim · July 19, 2011, 16:59

So I've been doing this airfoil project for a while now, using different meshing programs, and here I am on ICEM. The idea is to mesh a 3D airfoil in such a way that you can also model the end of the wing (tip). So (http://tinypic.com/view.php?pic=2yo3g4j&s=7) is the meshed out airfoil system, using blocking. Basically, the fluid area is meshed out, and the airfoil itself is left blank, with the "fake" airfoil filled in within the fluid mesh. All looks well, the mesh quality is high throughout, EXCEPT at the tip of the wing (http://tinypic.com/view.php?pic=33yg5xi&s=7). This area is in the lower, "fake" airfoil section. Is there a way I can fix these elements? Maybe change them from hexa to tetra just for that area? I'm open to suggestions

I guess what I'm trying to do is fit a square peg in a triangular hole, so to speak, using the hexa to model the inside of that faux airfoil. I would imagine this would make some pretty iffy consequences in the solver, that is why I feel there must be a better way to do it.
