Multidody Mesh

fher1608 · June 21, 2011, 11:00

Hi, I'm trying to study the aerodynamics of a wing, and for that I have created a mesh made of 4 zones (this is because I want a very precise control of the mesh). Once the mesh is done and with high quality I entered it in fluent.
The problem is that once in, the contact walls between the 4 bodies are recognized as walls and not as fluid. I don't know how to change this and I need some help. Any idea?? Thank you very much

The thing is that I'm using a sweep method mesh, and before doing that there were 4 sewpable bodies, and after doing that just one.

ok, if you have only 4 bodies and is not an annoyance to connect the faces manually, you can connect adjacent faces using a mesh interface instead of a multibody part.

See "Using non-conformal mesh" tutorial (Fluent help) for more info

I tried creating a part from the 4 volumes and also I named the hole stuff. The thing is that, before doing this, there were 4 sweepable volumes, and before doing it there was only one, so I couldn't mesh the geometry as I wanted. How can I avoid this from happening?
