DPM transient laminar flow over a cylinder

I´m trying a simple case:
A flow over a cylinder at Re=80, with unsteady formulation.
I turned radiation scheme "do", so that the cylinder send radiation.
Then i inject particles to measure uv radiation that every particle had received.
I´ve doubts and problems:
1- Should i turn on dpm after the flow and radiation convergence or should turn before any simulation.
2- I inject particles from a surface "inlet" and i didn´t change start and stop time. should ?. The problem is that if i check unsteady particle track it happens nothing (literally), but if i uncheck that optinon i can mesure radiation i every particle. i don´t understand waht i´m doing wrong.
Notice that I have and udf implmented that mesure this quantities and works real fine.
In advance thanks.

once you will use dpm , i guess you have to give ESCAPE condition on the "inlet" and "outlet"
try to give a certain start and stop time and see whether your getting any particles inside your geometry.
im not sure but it may help,
