Not yet. I'm going to try out the source/sink tutorial this weekend. For the picture above, I created a rectanglular block of water and let the sim drop it into the tub to create a chaotic splash. I ended up having to triple the thickness of the bathtub to keep the water from going through it. I did the same with the shower curtain, but it still went through, so I just chose the frame right before the water poked through. I haven't experimented with higher thickness values yet. One thing that's really annoying is that if when you parent and unparent complex geometry to the FluidOS Domain, it takes some time, so it kind of impedes workflow if you tweak a lot.
