Pre foam by texture in the beachtank

[mauropetrelli 0]

I'm trying to add foam in the first frame of my simulation.

I'm using a scatter node to distribute the foam in the first frame,My idea is to inject these dots into the whitewater solver so that they are calculated dynamically. I want to do something like this https://vimeo.com/162173918. Try to make an object merge of the dots on the Whitewater source node but I can't make these dots become foam particles

 

thanks !
