Hello all
I work on a project where I want to emit fluid from particles like rain. I create a sphere and scatter some point and in pop network emit particles. Setup done
Now my question is I want that when particles comes in flip solver grid it's became fluid(drops). Like in attachment it made in phoenix fd.and I want this same in Houdini.

I dont understand the question 100% but have you looked into the pop-fluid-node (https://youtu.be/K7UAVUzRP4Q)?

Alternatively you can just use the FLIP-Source-SOP on your sphere and import it as a volume source to the flip solver (https://youtu.be/ZuUW2kiLeAU).
