 April 20, 2012, 10:37 How to create 2 separate Surface Bodies? #1 New Member   Andrius Join Date: Mar 2012 Posts: 23 Rep Power: 7 I would like to know how I could draw up 2 discrete surface bodies without connecting into 1. I am modelling a gas flow in a tube fitted with a bluff body entering atmosphere. I have two tube inlets and 2 outlets entering the atmosphere as shown: Many thanks

How did you know this was made in gambit?

This is all handled by whatever you used to generate the mesh. So how did you generate the mesh / model?

You cannot build geometry/meshes in Fluent. So my question is, what did you use to make the mesh and build the geometry? In other words, your inquiry is not appropriate for the Fluent section as it does not pertain to Fluent at all.

I then used Ansys work bench Meshing to generate the mesh. The problem I have in Fluent that it reads it as one piece... Last edited by Matlab69; April 22, 2012 at 18:47.
