Hi there, 

I've simulated a rotary drum which has an inlet and outlet. 

A certain amount of particles are injected into the dryer from an imaginery inlet and they will exit the domain from an outlet. 

I can obtain all the mean residence time of the particle easily. But what is more important to me now is to figure out the residence time of every single particle. When I'm trying to plot the Particle ID vs residence time, it does not give me the residence time of all particles, I don't know why. 

Please let me know if you have any idea that how I could sort out this problem. 

 

All the best,

Hello,

Please apply the settings for Particle tracks properly. Ensure the particle tracks travel all the way upto the outlet. You may observe some particles terminating at any random wall too.

You can also try to check the DPM out file and try to increase the maximum steps.

Hi there, I have not used the DPM yet, is it a part of Postprocessing setting? is there any tutorial for that?

Just for your information, I'm working with Rocky ansys ...  I haven't coupled it with CFD Fluent.

Rocky is somewhat different to Fluent. I'm fairly sure there's a graph function for age as particles leave the domain, but it may be buried in one of the Tutorials you access from Help. I'm not aware of Rocky tracking an ID though, but am somewhat out of practice with it.
