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.

Hello, excuse me, I wanted to ask if, when doing the two-way coupling with the ROCKY DEM software, I should also consider that the first cell must have a y* greater than 15.
In my research I am analyzing everything related to collisions with the walls of the pipes, so analyzing everything that happens close to the wall is important.
However, I have this doubt since in the ROCKY manual they mention that we should have cells larger than the diameter of the particle. I would appreciate it if you could help me with this question; thank you
