Hi everybody and thank you for reading my thread,

Is it possible to measure the velocity(speed) of the particles in specific part of the particle simulation? Or at least measuring the velocity in general?

Thanks in advance.

Solvers that update particles usually also update particle v attribute which is velocity per second

If you want to compute speed, you can compute length of this velocity vector

Thanks a lot Tomas,

I was asking for doing this at DOP level and there is a particle speed limit if I remeber correctly but this also helps and does what I was looking for.

Still out of curiosity can I measure and do some extra things inside of DOP?

You can use that code (or any) in POP Wrangle DOP or Geometry Wrangle DOP
Which will update f@speed on your particles and you can use it to control POP nodes or custom stuff in wrangles, ...

Maybe this helps:
