Particle residence time distribution
 

Please help me.
I am interested in particle RTD.
I have included Lagrangian multiphase model, created massless particles Lagrangian phase as also track file.
I have the track file, but I can not read, export data from it.
I have tried to make an XY plot at the exit with Track:parcel index as x, and Track:Particle residence time as y. But I dont get a line. WHy?
I have tried also with tools/tables, but a column with anything from the Track is empty?
