[ANSYS Meshing] The Generated Mesh Does Dot Capture The Edges of Wing

mrh111 · September 20, 2016, 06:53

Hi everybody,
I have used "skin/loft" to generate a wing with 4 airfoils but when I mesh the wing, the generated mesh does not capture the edges of wing.
I use Curvature for advance size function and I've increased Relevance up to 100 and adjusted Relevance center to fine and decreased the Curvature Normal Angle and also I have decreased the face element size but it wouldn't efficient.
I hope someone know the solution.
Thanks in advance.

Change the advanced size function to 'fixed'.
Change face sizing behavior to 'hard'.
You can also introduce edge sizing for all the edged [optional]
Initially disable the inflation layer. Once you get the mesh you desired, you can turn it back on.

Try these and let us know how it went.

Vasava, I really appreciate your suggestions.
I tried them. After regenerating the mesh with default size, problem solved.
But some roughness arose when I decreased the element size of edges and refined the mesh.
I'll upload the geometry, its very kind of you if you look at it.
If you couldn't open the file let me to change the upload center site.
thanks a lot.

I will see, what I can do.

I am using spaceClaim and am not able to open your CAD file. Could you convert it to STL or STEP file?

yes, sure, I've just zipped it.
