[Closed] WSM wave and particles

Hello,

I am trying to do a simple cartoony wave.

I used a plane with an animated WSM Cyl FFD
I try to add foam on the wave crest, so i made a small band where particle spawn
i use a simple position object PFlow
But the particle doesn t collide with my wave : with a collision operator and Udeflector

i tested some work around, and nothing work.
I Will try with a baking animation within a morpher

How can i make my WSMed plane collide with particles ?
