Hi all,

I've been looking in the manuals for information on the particle tracking file. Does anyone know what the variables that CFX outputs into its .trk file from particle tracking. I tracked one particle stream and opened the .trk file in notepad which gives this:
105

2.3706595E-04 6.5253494E-14
.... and so on...

Also is there a way to extract certain particle variables out and output them into a file itself?
Thanks!

Hello,

I am conducting a steady state analysis of pump and I am looking to track the particles (more or less same example as butterfly valve with erosion tutorial). The problem is I am only generating blank particle file. The .trk files are simply empty. Also, the .trk file is only created for 1 particle with pT1.trk file. How do I keep track of all the 20 particles? Do anyone has a way around it? or, helpful links?

While I am at it, would it be possible to generate impact velocity data of those particles from CFX?
