Hello, I want to reformulate a question that was unclear.

I choose to inject the particles between 0 s and 1e-02 s.

Afterward I want to follow the particle for the 2 seconds of my unsteady RANS simulation.

Unfortunately, I can only follow my particles for 1e-02 s as if they disappeared at the end of the injection.

But that's impossible as this is a closed system and the walls reflect off the particles.

Do you know what I should do?

Many thanks in advance.

Hi,

I have some kind of identical problem and would appreciate any answer, too.

I want wo inject 1 single particle of defined size and temperature at the beginning and then only want to track this particle.

Thanks
Martin

If you run your simulations and export - particle history data.
Open CFD-post and import the particle history data from Fluent, you might be able to see that you are looking for.

Maybe this video can help: https://www.youtube.com/watch?v=nVrD...l=RaefKobeissi
