Steady state particle tracking?
I had used CFX for transient particle tracking problems, which is very time consuming since very small time step may be required. Can CFX be used to perform steady state particle tracking? if so, how to do it?
Fluent has the Discrete phase model (DPM) for the steady state analysis, which is very convenient for particle residence time distribution analysis. Does CFX also have the same capacity? Thanks, John |
Yes, CFX has steady state particle tracking. Some tutorial examples use it, have a look there to see how to set it up. I do not know exactly what residence time analysis fluent can do but I suspect you will be able to do similar analyses in CFX.

Thanks. Could you please advise which tutorials have such information? I checked the version 10 documentation and could not find any related info.
Regards, John |
I think several of the tutorial examples, even back in V10, used particle tracking. You will have to look through them to find them as I have not had V10 for many years.

steady state vis-a-vis transient particle tracking
Hello everybody,
I want to understand the differences between these two ways of particle tracking? Are the real particles represented by means of Parcels for steady state tracking, too? what is different for the structure of the particle tracks file for both cases? It would be great, if someone experienced in Particle Transport Modeling in CfX could answer these questions :) Thank you! |
Probably the best way of answering this question is to do a quick steady state and transient particle tracking simulation and have a look at the output files.
And yes, for both steady and transient particle tracking the modelled particles represent a large number of real particles. |
