Hi guys, I have to simulate a 2D gasoil injection (for a diesel internal combustion engine) in a geometry constituted by a rectangle 100 mm of widht and 60 mm of height. In this rectangle there's just air at normal conditions (so it's a closed ambient). I should use an atomizer between the ones available in Fluent. I have mass flow rate (sperimental results) and duration of injection, but every time i try to setup a unsteady simulation there's absolutely no particles in the visualization of Particle Tracks. Does anybody know how to setup the problem?

In the particle tracks tab, choose the step-by-step report and print out particle positions to the console. What happens to the particles?

Thank you very much. I got the visualization of particles, i just had a mistake on the setup of the problem!
