Could I get some clarification on what separates a stable fluid versus an unstable fluid? The simulation does well to simulate the liquid motions, but I'm curious what would happen if it was unstable. Do unstable animations just not render?

An unstable solution would likely lead to a simulation that can quickly get out of hand - where small perturbations calculated with our equations can lead to large variations, breaking down the "realism." A stable solution would allow us to maintain within the approximate area even with perturbations, making it smoother.

^ adding onto alvin-xu-5745, unstable fluids would not converge to a still equilibrium. For example, the small perturbation would not necessarily eventually lead to a still fluid if the fluid simulation was not stable.

@sberkun Thanks!
