Fluent reading wrong mesh type
 

Hi there, I am relatively new to CFD and the forum too. I am currently carrying out a project on the front wing of a race car and I'm at the stage where I'm adding the moving road to simulate a wing in ground effect.

I have been using ICEM to create my mesh which to the eye looks fine however when I export into fluent it automatically selects 3d when the mesh I created is a 2d mesh. I have associated all the edges to curves for the domain and exported a 2d mesh before entering fluent but still decides the mesh is in 3d.

I have previously been learning to mesh through this tutorial: https://www.youtube.com/watch?v=3VuZiDIl704 which was great and easy to follow. However, this tutorial was in free space and now I'm having to add in the ground which has created a world of problems.

I was wondering whether anyone had any idea what I could do to try make fluent read the 2d mesh or if there are any suggestions into what I could do to my mesh to allow the exported file to be read correctly by fluent.

Any help would be greatly appreciated!

Many thanks,

Tom.

Is it in XY plane?
