x_velocity of particles
 

Hello,
I want to write a udf that needs x_velocity of particles.
Is there any macro which refer to x_velocity of particles?
Thank you for helping me.

Are you using DPM?

yes i use DPM.

I think you could use P_VEL(p)[i] with i= 0, 1, 2.

Hello Nikiii,

Have you succeed to implement your udf ? I'd like want to try a similar case)
