Hi!
There’s no explicit “bouncing” implemented in Obi, the collision model has no restitution parameter. There’s only two possible sources of bouncing: compressibility, or depenetration.
If the fluid is too compressible, it will compress when you move the container up, then decompress when you stop (giving it in a bouncy look). You need to use more substeps. (In the ObiFixedUpdater)
If the fluid gains velocity because it starts frames inside of a collider and has to be taken out, you can reduce the max depenetration velocity (in the ObiSolver).
A video of the issue would help, as I can’t really tell for sure what you’re referring to. Cheers!
