I am trying to make a beach. When I tried simulating the fluid (2.82 mantaflow), it went mostly well. However, I noticed that the water would stick to the entire floor when all I wanted is that around 2/3 of the ocean floor is covered.
As you can see there is a sloped down part, and I want some section of it to not be covered by water. However, it seems that if the water touches something, it will never recede from it leading to this unrealistic simulation.
I baked it at 100 resolution and then baked it as a mesh to make it easier to see. If you need more information please request it.
