The short answer is that one the sphere (the bowl) on the volume initialization you change it to ‘shell’ . These steps will get you a decent sim:
- On the cube (the domain) select it hit ctrl-A , choose ‘scale’ (apply the scale)
- On the sphere, in the solidify modifer, change the offset to 1 (from -1)
- On the sphere, in the sim, change volume init to ‘Shell’
- On the cube, in the domain settings, change viewport diplay to ‘final’, change the resolution for final and preview to about 110-150
- bake it again.
You can add a subsurf modifier to the cube (after the sim) to smooth it out some. Also set the shaing to smooth of the domain cube.
