3d mesh around a wing using ICEM
 
Hi,
I'm trying to do a structured mesh for a 3D Wing geometry on ICEM. i have made a wing geometry and imported it to ICEM using the iges format. Next, i have a rectangular flow domain using the create point on the geometry. Furthermore, i have created a block '3D bounding box' and associate the edges. Now, how to proceed next? I have been unable to generate a volume mesh? When i use the Update Mesh button, it only generates the mesh on the surfaces.. Any ideas would be appreciated as to what is the problem..

Furthermore, can anybody tell me how to create a simple o-block around the wing. My wing is tapered.

Thanking in anticipation.

Late better than never?
 
Sorry, I am a month late getting to this question (I have been busy). Perhaps it is too late and you have figured it out and moved on... Or perhaps not.

There have been a few other questions on meshing wings recently, so I will try to take care of them all at once.

Can you tell me a little more about yours? Is the tip rounded? Is the trailing edge sharp, flat or rounded?


Also, reading your question again, perhaps your problem isn't with the topology... But is with getting a volume mesh... In ICEM CFD Hexa, we initially work with Premesh. This is more rapidly generated than an unstructured mesh and can be the precursor for either unstructured or multiblock structured mesh. If you want either of these other formats, you should right click on premesh and convert.

If you convert to unstructured mesh, it will load an unstructured mesh that you can export to your solver.

Perhaps going thru some tutorials would help with these procedural issues.

Expecting for your new post!
airfoil: round tip, sharp trailing edge
and the wing with same root and end airfoil, with an round end cap.

ICEM beginner
 
:confused:
hi I am a beginner working with ICEM and I have a problem.when I,m trying to use orthogonality method for my sketch which is an airfoil in a designed domain,my mesh will be distroyed and I just don't know how to fix it?please help me
