hi everybody, i' d like to know how can I estimate particle trajectory. I mean that I have a domain in which droplet enters together with tha gas phase. The droplets should fallen down in the ground when they reach their maximum height. the fact is that the particles are allowed to escape or be trapped when they meet a boundary. But I don't want that thay meet the boundary and I do'n t want that their trajectories are considere as incomplete. How can I do? thanks a lot antonietta

hi

inoreder to make your trajectories complete you have to make the following rule

the product of step length factor and maximum number of steps should be equal to your total cell elements(iN DPM)

if the particles don"t want to meet the boundary u can use the boundaruy conditions like the particle stouching the botoom wall are reflects back.

hope this will helps u
