When we added the scenes into Fluent the "show mesh" option in the panels stopped working in the way it used to. Instead, create a mesh object showing all the walls/inlets etc as you want to see it (if you want to show the wall faces do so, transparancy comes later). Then create the particle scene. Finally, in the Display section in the tree create a Scene with the mesh and particles. Create the animation of that. The image summarises the steps.  

It's a more long winded method than before, but the results are worth it.
