Reply To: Sedimentation of one particle


Dear Henderson_C,

first, please verify that you are meeting the general LBM stability requirements (according to e.g. [Krueger17]( You should then set your resolution in such a way that your particle is represented by a sufficient number of grid cells (e.g. 10 cells in diameter). You can find out the specific minimum requirement for your setup by conducting a grid convergence study and evaluating the respective error of e.g. the hydrodynamic force in the sedimentation direction. For a more detailed description of sensible parameters, I would like to again refer to [Trunk21]( or similar literature.
