Default Particle size distribution-concentration contours

Hi all,

(((((Fluent6.0,DPM.Inert particle spray.))))

When I use uniform(single) particle size, i can display the contours for DPM concentration at required surfaces.

But if i take size distribution using rosin ramler method,

There is no value returned for DPM concentration and i can not display the DPM concentration contours.

Anybody know why this is so. How can I get this concentration value when i use size distribution.

Thanks for your time.

Sir, what size of particles do you use? I am also doing this kind of project, but when I inject small size inert particles, for example, 20nm, all particles are evaporated. I am not sure what happens here, could you tell me how to solve this problem?

Ann, I think it's a problem of Fluent 6.1. particles do not simply evapolate in FLUENT 6.0.
