N2 - The Discrete Element Method (DEM) is widely utilized to solve engineering problems. However, validating DEM analysis is still challenging except in simple cases. To address this issue, the TC105 Japanese committee conducted the round-robin test using 3D-printed particles for angle of repose experiments. To further develop the project, this study aims to quantify the impact of DEM input parameters. A series of DEM simulations were conducted using different program codes, and the sensitivity analysis was performed through four different methodologies. The results qualitatively indicated that the friction angle between particles had a dominant impact.
