# Why does fluid (water) stick to the top of an obstacle?

In our simulation, Fluid (water) drops on an obstacle and splashes. It mostly works fine, but there is noticeable part which remains on top of the obstacle! In reality, there should be no water there, as you can see the shape of the obstacle is very rounded.

Is there a setting we are missing?

Our settings: Obstacle is no slip. Fluid is free slip (which, it was assumed, forces water not to stick to obstacle). Water. Baking resolution is 150.
