how to give particals in cfx?i.e. i have in my problemt ther are two phases.one is air and other is paricals.How i can apply in pre and how to proceed?and what is partical tracking in post? Thanku all.

U can give the paricles in the domain first u decide in which u zone u have to inject the particles and decide the size of the praticles and the distribution. U can see this in the domain specification or the boundary conditions.

comming to the post "the particle tracking is that u can trace the path of the particle which you have injected into the domain.
