Hello, colleagues.I am new to CFD and I am trying to run tutorial 3.5, 3D fluidized bed(DEM), but I have encountered some confusion.
I successfully ran this case according to the settings in the tutorial, but after trying to reduce the solid diameter from 0.005 in the case to 0.004, I found that the solid particles were basically not fluidized. Of course, increasing the fluid inlet velocity significantly can continue to fluidized the solid, but is this normal? Is the influence of particle diameter so significant?I only changed the solid diameter, everything else is consistent with the settings in the tutorial

Hi guys, has anyone noticed my problem? Does this mean that the grid size in the tutorial is not the right size?
