Hi Ian,

i tested your idea, but unfortunately it is not working well. The tracer is still moving in x-direction (with the wave), even though i have this movement constrained. I found a method using the volume of fraction in this paper (https://lsdyna.ansys.com/wp-content/uploads/sites/2/2022/12/validation-of-the-ale-methodology-by-comparison-with-the-experimental-data-obtained-from-a-sloshing-tank.pdf). 

If you have another solution, I am happy about any further help.

Jonas
