When aiming to seamlessly integrate a fluid simulation into a larger scenario (like an open ocean), careful attention must be paid to boundary conditions. In particular, one must implement special "non-reflecting" boundary conditions, which dissipate out-going waves as they exit the simulation. Unfortunately, the state of the art in ... lit infrarougeWebGeneralization: reflecting boundaries¶. The boundary condition \(u=0\) makes \(u\) change sign at the boundary, while the condition \(u_x=0\) perfectly reflects the wave, see a web page or a movie file for demonstration.
