I'm having an issue with my fluid simulations. I'm a beginner, so I might be missing something obvious.
I'm trying to fill up a cup with water, but the liquid is behaving very strangely (see below).
Most of my settings are default, except the cup's volume init is shell and the slip type is free slip (to prevent sticking). I've made the problem less severe by increasing the resolution of the simulation, but it still sticks out of the cup.
