Technical Note
The iWave approach to simulating surface waves is fast and efficient, but suffers stability and artifact problems. By rephrasing the algorithm to employ two first order diffential equations for the displacement and velocity potential, and using an exponential solver, much more accurate simulations result. Importantly, the solution is free of the stability and artifact issues of the previous approach, and maintains high efficiency and flexibility.
