Non reflective boundary condition
I'm new to OpenFOAM and trying to model the partial coalescence cascade of a water droplet using interFoam with a barely modified damBreak scenario. I want the water waves created by the cascade to leave at both sides without being reflected. What boundary conditions do I need to apply?
At the moment I just use a sufficiently large width to solve the problem. This approach, however, increases the runtime.
A screenshot of the beginning of the simulation is attached.
