Hello,
I am trying to generate a bed of particles on this hopper so I can then turn the auger and force down the particles in a different simulation. The hopper will move across a platform and dispense the particles by rotating the auger. The issue I am having is that the particles I generate do not rain down and settle onto the concave surface of the hopper. Instead, they just stay level with the surface they generate. I believe this is a problem with my boundary conditions, but I have messed with all kinds of boundary conditions and I still don't get results. The pictures below show details of my issue. Please share any tips. I have a box and a base generated as shown.
Thank you for your time and consideration
