Particle Transport and Mesh Cell Size -- CFD Online Discussion Forums

March 22, 2012, 06:01	Particle Transport and Mesh Cell Size	#1
siw Senior Member Stuart Join Date: Jul 2009 Location: Portsmouth, England Posts: 735 Rep Power: 25	Hi, For an incompressible flow with particle tracking is there guidelines on how small mesh cells should be? For example: should a mesh be sized so that a particle is expected to move cross a cell face per time step? Or perhaps move every 2nd timestep? Thanks
