Problems of Icem meshing about Conical Forebody

raja2010 · December 5, 2010, 21:02

I want to meshing a conical forbody using icem and have tried a lot of times on it, but the front part is still not good enough to be computed by Fluent. I use a Blunt-nose forebody and O grid in icem. Is there any tutorial about meshing conical forbody?

if you can post some images of the geometry and the blocking you did, it will be usefull to understand the problem exactly.

Right, pictures would help... I don't think there is a tutorial, but...

Here is one of mine from a few years ago. I couldn't find the file to smooth it and take better pics, but these rough ones should give you some idea...

Here is the hexa version...
