I'm new to these forums and somewhat new to CFX but I have read through as many posts as I could before posting. I am trying to get particle track statistic for residence time studies using CFX and am having trouble reading the exported data. I am exporting Particle Time and Particle Traveling Time but the exported data (as txt files) is too confusing to read.

I have injected particles at 100 particles/s with a no slip velocity at the inlet with a simulation time of 10 s (transient) and have no issue viewing results in CFD-Post. The problem is, I would like to export data for only the particles from the first timestep of the simulation but can not figure out how to do this.

If there is a better way to do this from CFX-Pre I will re-run the simulations but I'd prefer to just interpret the data I already have. My guess is it is in number of positions maybe with a function but I do not know where to go from there.

Hope someone can help!
