Default Intialization of particles velocity in DPM

Heu everyone,

I wrote an UDF to initialize the particles velocities (u, v and w) to that of the flow, when these particles are injected into the flow (using surface injection).

I built and compiled the UDF and then hooked it (when I created the injection). But, in "Point Properties", velocity still equal to "0" ! Moreover, when I ckecked the results, I fund out that the the velocities are intitialized at "0" and not at the velocity of the flow ! PS. I load the images to be more clear.initialization.jpg

thanks for your answers and help
