Hello, I have been running some granular flow simulations with the GPU module. When comparing my results to other similar work that uses other codes, my results are not aligning with those from the other works, even when the same material properties are used. I cannot post my results publicly on the forum, but can share them with someone from the Chrono team over email.
Essentially, I am seeing that in previous works, the streamwise velocity of particles is continuously decreasing from the center of the granular bed towards the wall. In my simulation, however, the velocity of particles is essentially the same across the bed, except for the particles that directly touch the wall. The paper I am comparing to is: X. Sun, Three-Dimensional numerical simulation of quasi-static pebble flow In particular from this paper in Figure 9, my results look much more like the Hookean velocity profiles than the Hertzian profiles that agree with experimental results. Any help on understanding what is going on would be appreciated. Thanks! David -- You received this message because you are subscribed to the Google Groups "ProjectChrono" group.
