  Hello everyone, I'm simulating a microfluidic spiral with a rectangular cross section. I used a UDF to include the wall and the shear force but when I simulate i see theta the particles stay at the outer wall and not at the inner as should be. I see the dean vortex but i don not why they are so small and are not able to push the particle towards di inner Wall. Someone have some any ideas?
  Thanks in advance

  Please post some images. I assume you set up the fluid & particle materials correctly? How big are the particles relative to the zone & mesh?
