It is interesting how semi-Lagrangian advection the goal determines the movement of fluid particles over a certain time interval using a computational grid. Unlike other methods that track the flow directly, semi-Lagrangian follows a Lagrangian approach by tracing the trajectories of particles backward in time. However, how does this backward approach improve simulation accuracy? Also what interpolation methods are normally used to determine values as particles move through the grid?

How does Semi-Lagrangian advection differ from Eulerian approaches for fluid simulation? What advantages does it offer in terms of stability and accuracy for simulating fluids?
