DEM Particles protruding through walls
 
Hello all,

I am currently trying to model a randomly packed bed geometry, and am using Star's DEM tools to generate the particles. Everything works just fine until I need to create geometry parts for each sphere. Seen in the picture below, spheres are protruding through my wall surface (even before transforming them into geometry parts), and this is causing me to be unable to mesh correctly later on down the line.

I've gone through the tutorials, plus followed some other videos online, and have yet to find an answer to this problem. My mesh size for the surface is larger than my sphere size, so there shouldn't be a problem between the sphere/wall interaction.

Thanks!
