November 8, 2018, 12:43	Sedimentation velocity in MFIX	#1
mairy New Member Muhammad Umair Join Date: Feb 2018 Posts: 2 Rep Power: 0	I am currently trying to model sedimentation using MFIX-DEM with periodic boundary condition assumption. Is MFIX software suitable for simulating sedimentation phenomena? The problem I am facing is that MFIX is predicting the sedimentation velocities 100 to 1000 times of the expected value. I cannot understand the possible reason behind this discrepancy. The system I am using is a rectangular periodic box. Gas-Solid system is used with a solid volume fraction of 0.02.
