Hi All,

I'm trying to write a journal file which tracks particles flowing through a geometry in a steady state flow. I am able to do this through the GUI journal commands by displaying injections and tracking particles on screen, and summary reporting the fates to a text file. However, I believe this bottlenecks my simulation speed and I want to write one in text-based user interface only.

Does anyone know the TUI commands for one-way coupling DPM injections and reporting their fates to file (without displaying them)? Should give me something like:


Escaped Incomplete
Zone 5 - 50 0
Zone 4 - 45 0

Thanks in advance. -sjc

In case this helps visitors after today - although I assume I'm too late to help the original poster...

You need to set up some parameters first:
1) /display/set/particle-tracks display? no
2) /display/set/particle-tracks report-type summary
3) /display/set/particle-tracks report-to file
4) /display/set/particle-tracks history-filename "your-file-name-here"

Then, you need to use the (counter-intuitive) command:
/display/particle-tracks particle-tracks <color-by variable> ("your-injection-1" ...) <min-of-variable> <max-of-variable>

Yes, you need to give it the display variables even with no gui. But this will get you that summary. In step 4) above, you could use %i to save the iteration step in the file name and therefore keep a history for each tracking command.

Note: the following applies to ANSYS Fluent v16.x. The TUI commands and syntax could be subject to change in the future and also may not be the same in versions prior to v16.

Thanks so much, this is exactly what I needed.

Hallo.


Thank you for the input. I really appreciated it. Just an remark. My goal is to write a step-by-step dpm summary report and this would be a working example:

;-- Report Particle -----------------------------------------
;-- Report to File
/display/set/particle-tracks/report-to file
/display/set/particle-tracks/report-type step
/display/set/particle-tracks/display no
/display/set/particle-tracks/history-filename "dpm-data-inj01.his"

;-- What to report
/display/set/particle-tracks/report-variables
particle-mass
particle-x-position
particle-y-position
particle-z-position
particle-reynolds-number
particle-temperature
q

;-- Which injection
/display/particle-tracks particle-tracks
;-- Particle tracks colored by>
temp
;-- Injection name(1) ["inj01"]
inj01
;-- Injection name(2) ["inj02"]
()
;-- minimum value (k) [300]

;-- maximum value (k) [1700]


Best Regards,

Can you export the file in xml format
