A probelm about the 3D view

Hello,
I met a problem. I had a mass flow of particles on the right side of this 10m 3D fluid bed. And in the 3D view, there is no particle inlet image display shown. But there the has the particle inlet image in the 1m fluid bed which has the same condition except the length. And the region of the particle inlet is only 6 cm. I don’t know the reason.

And I have run it for almost 8 hours.

Have you actually reached 1 second of simulation? You are writing VTK files every 1 second so you won’t see anything before that.

I changed vtk_dt=0.001 and I see the solids coming in.
