We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Thanks Rob, 

Where do I define the free surface ? My domain is a square box of height 100m. I want my watersurface at 50m. I have placed my body at an intial roll displacement of 5 degrees. Since I am not using open channel flow or waves, in which boundary condition can I set the water free surface?
