calculate the average velocity of particles
 

how to calculate the average velocity of particles at every time step

I have a question whether FLUENT DPM could calculate the average velocity of particles at every step by UDF.

for example: I have 1000 particles injected in the channel.

at 0.1s, particle 1 has (x,y,z,...velocity)

particle 2 has (x,y,z,...velocity)

particle 1000 has (x,y,z,...velocity)

how we can get the average velocity for 1000 particles at this time step

at 0.2s,

and so on.

Thank you so much
