3d mesh
 

Hi
I have a 3d duct and want to simulate flow through it.
I have created all the faces in GAMBIT,closed all the edges.Iam now confused how to create the fluid inside and mesh the fluid to analyse the flow.:confused:

hi
i simulate an air-intake of Mikoyan MIG-AT with gambit an i do this in this manner

as you see i make 3 volumes : wall inlet(pressure far field) interior volume that air flow in it.
you can mesh it as unstructured free mesh and after specifying the boundary condition you can Analyze it with fluent or cfx or any othr solver that you want to use but i suggest fluent

Once you created all the surfaces, you can create a volume.
Gambit will set this volume automatically as Fluid
