Reply To: HBLM for stokes drag force simulation


Dear Zhangshi,

what is the particle size, i think you need at least 10 cells per sphere diameter to depict the sphere correctly. The Stokes assumption also states that the fluid extends infinitly in all directions (i.e. there are no walls). This has been investigated in some paper finding that you need several times the sphere diameter as distance to the walls in all directions.

Best regards
