[Question #699070]: Effect of particle size on noise in the results
New question #699070 on Yade:
I am new to DEM and I have very little experience with YADE and DEM. My question is more of a DEM nature rather than YADE. I hope someone would be able to provide some advise.
I am simulating MBD-DEM ( movement of a bucket into a stockpile) and I noticed that when I use large particle sizes (300-400mm) the results are noisy. I was advised to repeat the simulations by slightly shifting the bucket to right and left to evaluate the error and the error was huge (around 40% error compared to the simulations with initial location of the bucket).
I am not sure what could be the source of such error. If it is an issue with DEM then how someone possibly could simulate the large particles using DEM.
I appreciate any advise or resources in advance.
