Problematic Geometry

marcoymarc · January 17, 2013, 08:59

Hello Guys.
I know there are several threads about problematic geometry and i tried some solutions with no result (different methods and smaller elements).
I want you to see my issue since it sounds very strange cfx mesher reports an error message only for 1 of the four elements i'm trying to mesh, since they are perfectly equal.
Again, sorry for my English.
Every suggest will be helpful.
Thank you

Well, if i take a single element and try to use a sweep method, everything works fine.
When i put em together and i define a sweep method for each one of them, i can't complete the meshing.
Consider that the four elements are placed in a parallelepiped (that's hidden in the linked jpg). I think there are some issues at the interface.
Any ideas?
Which method should i choose to mesh the "container"?

This should be asked on the ANSYS geometry and meshing forum.

Ghorrocks i did it. Even if the error suggested something else, i found a little issue in my CAD model and solved it redefining some bindings. Thank you anyway.
