Thank you, Ian. Maybe you can also answer this other question I have. I am trying to embed a pile into the water surface so that it is partially submerged at t = 0 sec. To do this, I believe I need to remove the water from the footprint of the pile and replace it with MAT_VACCUUM. The issue is when I try to fill the footprint of the pile with MAT_VACCUUM, much of the water remains behind (see photos 1 & 2). This creates instabilities when I run the model, and disturbs the water surface (see photo 3). What would be the correct way of modelling a pile embedded in water ALE elements? (The water in the below photos is no longer yellow, it is brown)
