HI I'm new to Houdini, I've been tasked with learning it for work as we no longer want to use Phoenix FD for fluid simulations. This is hopefully a newbie issue and therefore an easy fix. I had a flip tank working and following my boat well enough, but since I have tried to add ocean spectrums I keep ending up with particles flying directly upwards from the waves as if there's no gravity. I've attached a screen shot, what am I doing wrong other than trying to learn Houdini after 20yrs in other software
