Hi. So my issue is this. I've essentially created a box out of five deflectors (bottom,back, front and two sides) that holds the particles that have fallen from above it (using a 'force' for gravity). When the box is filled to my satisfaction, it is my intention to tip the box and have the particles fall out. All of that is fine and it essentially works except for one thing: when I move my box horizontally (no tipping) all of the particles fall off (not through) my bottom and go through the side that that is opposite of the movement. I made sure that all sides of the box are 'going through' one another so there are no gaps. I guess my problem as I see it, the side is not acting as a deflector one the box is on the move. Any thoughts? I will include some images once I figure out a place to store them online for this purpose if it helps to visualize what I am saying.
