Hi -
I am trying to view particle tracking data in CFD-Post; however, when I try to upload a particle tracking file, my only file extension option is a CFX-4 Particle Track File (.trk). I'm doing my CFD analysis in Fluent. Two questions: 1. Can I generate a .trk file using Fluent? 2. When I write particle tracking data to a file in Fluent, the file extension is .his. Is there a way to convert that file? Thanks - Chris |

Hi,
This is from CFX-Post 12.1 documentation, regarding reading Fluent files: "The loading of particle tracks (either track data in the data file or separate track files) is not supported." I do not remember seeing anything new in this area when I read the release notes for v13, but I am not entirely sure. I would also appreciate if anyone knows more about this, maybe there is some workaround? Cheers, Reine |

i'm trying also to display particle tracks in CDF-post and Fluent. In the CDF-Post user's guide it is stated that we need a " appropriate Fluent particle tracks XML file" to import in CFD-Post. To create this file, the ug says that we have to refer to the fluent user's guide. I've read many times through the displaying and writing of particle tracks files but there is nothing about this XML file. I also tried to import each format that Fluent writes about particle data. it doesn't work. any hints or suggestions? |

Hello everybody!
I used the XML format for particles tracking on Ansys Workbench 13. There is actually a new feature in the "Calculation Activities" menu, in the "Automatic Export" field. Click on "Create" and you should have " : "Particle History Data Export" then select the CFD-Post check box and set your exported variables as you want. With this, the exported file is in .xml. My problem is that I found this format very heavy and when you have a lot of particles like I have (around 8000), and if you want to track each at every time step, the file size is increasing of about 2 MB/t_step ... So it's a problem for data treatment afterward but it is another subject. Hope I've helped you! |

Hi,
Can anyone suggest if I can track a particle after its formation in a reaction like precipitation. |

Hey people,
here is how to read in a .xml particle file form Fluent into CFD-Post: In CFD-Post you have to click at FILE->IMPORT->FLUENT HISTORY PARTICLE, then it will ask for xml. Hope I could help you. |

Hi, colleagues! Can you explain me my problem.
At first, I save case & data files in Ansys Fluent 14.0, then I read this files and further I import the particle track file in CFD-Post. And when I import the Fluent particle track file I get exception "Internal. Internal error detected: Unknown XML exception". Please explain me what I should do? Thanks! |

The particle summary report generated in Fluent is not supported by CFD-Post. Nothing that you do about it in Fluent will work with CFD-post.

you're quite right. One can not import .xml file through "particle track->geometry->file" cause it only support CFX-4 Tracks (.trk) file.
However, you can get the same particle track plot through "file->import->FLUENT particle track file" directly. Xin |

Hi All,
I am trying to create an animation of rain entering an air conditioner condensing unit in CFD Post. Problem: Simulate rain falling on an air conditioner Condensing unit placed outside residential apartments and observe water drops / film formation on critical electronic components inside the condensing unit. Models Used: DPM, Eulerian Wall Film I am done with the simulations. I need to create an animation, wherein the rain drops fall and enter in to the condensing unit and hit the components inside. However, if I import particle tracks from Fluent into CFD post, how much I try, I am not able to get particles etering inside the condensing unit. BUt, in Fluent, in DPM tracking (Pulse Mode), I can observe it. Is it possible to import multiple particle tracks file from FLuent into CFD post? Thanks |

I guess the quality of the animation I required was the only deterrent I had in using CFD Post. But I guess, we can easily import particle data from fluent into CFD post for post processing Regards Vignesh |
