Hello fellow Houdini artists,
this is my first post here. How exiting.
So: I am working on a FLIP sim where one liquid is pouring/falling into another. For the lower one I use a fluid tank (from the shelf tool) and the pouring one is emitted with a pop source.
I wasn't happy with the amount of splash I was getting. I wanted more but couldn't manage. Then I had the idea to give a bigger density to the pouring liquid because I thought more weight, more energy, more splash. So I ticked the "density by attibute" box and added a density attribute in SOPs. Then, suddenly, my fluid tank started to fall. I tried then to instead use a POP wrangle to add the density attribute but the same thing happened. Why? What a mystery.
Also, I wonder if there's another way to increase the splash in this setup. The only alternative that cam to my mind was to cache out the pouring liquid and then use id as a static deforming collider in a second FLIP sim with the tank.
Any ideas?
Either to solve the mystery mentioned above or other ways to increase the splash?
Thanks a lot!

One way to add more splash is to add a downward velocity. Rebuild your setup and don't mess with density. Instead, check the velocity box on the fluid source and type in a large negative number.

Hey,
thank you for the answer. I wanted to preserve the shape of the flowing stream though, but I guess I could modify the velocity just before it hits the surface using a stream and pop wrangle (or any other force pop). Will try that.
Thanks!
