Thank you sir! But I don’t know how to run the neighbor search more often.Do you mean make the neighbor_seach_n larger?
Besides,I want to know the minimal size of grid.I noticed in previous post that desgrid size should not be less than 2diarlm_factor(Grid-based neighbor search algorithm, why the desgrid size should not be less than 2*dia*rlm_factor?).However,in MFIX tutorials(hopper_dem_custom_psd),the largest diameter of particles ,the rlm and grid size are 3.33mm,1.2, 5mm respectively.Thus,according to the post, 2diarlm=23.331.2=7.99>5mm.So is it right?
Apart from that,In my case, I used pure granular flow. The largest diameter of particles is 3mm. I want to know whether it is right if I set grid size to 4mm?
