Particle Fate

Arturo Ortiz

Dear all.

I am simulating a system in which a liquid with diluted particles flows in normal direction to a sphere. I am interested in knowing how many particles are impacted in the sphere's surface. I've set up several simple cases, but no matter what I change ( density of the fluid or particle, velocity, gravity, etc ), fluent reports that no particles are impacted on the sphere. I think that for dense fluids that is correct because the fluid will deviate the particles when they approach the surface, but I've used air and the same happens. Any sugestions?, am I missing some physics? Thanks in advance
