When using the SQP method, particles are observed to disappear at the bottom surface. (The bottom surface is a wall, and the outlet is on the side.)
To resolve this issue, I adjusted the mesh, e_young, and several other conditions, but I was unable to find a clear solution.
Under the same conditions, when simulating spherical particles using the default DEM, the particles accumulate normally on the bottom surface.
Please refer to the attached file for the key conditions.
I would appreciate any advice on this issue.
