Default Coal Particle Tracking

Hello I'm currently trying to trace out each coal particle in Fluent. I noticed when I use DPM Particle Tracking, I'll receive a data file that begins with Time column,X-posiiton,Y..Z,... Temperature...Mass...Color by and so on. I looked at the file and noticed that the time goes from 0-7..seconds or so, the begin at 0 again and continues on down the column. Does that mean as soon as the time reset to zero on the data sheet, Fluent is displaying another particle?

Is there a way where I can just track 1 PARTICLE ONLY and look at its time, temp...distribution?

Thank you

Have you several injection points? Because I think that in the coordinates of zero-time row, you should find the injection position and diameter value, so you can understand if it is another particle from the previous one... fluid

Hello Yes, I have several different injection points. However, when I extract the particle, I extract from only 1 injection point. Within this injections 3000 particles were recorded. Is it a correct assumption that every times the "time" column reset to zero, you can say that it's now tracking a new particle?

Thanks

sorry, I'm not sure because the manual doesn't specify it, but i suppose so....

Yes when the time resets to zero it does mean that it is a new particle. Unfortunately with Fluent there is no possibility of tracking a single particle if you have multiple particle injections. I would second fluid's suggestion of looking at the particle dia and position to confirm that the tracking has changed from one particle to another.
