Just to share some experience with some calm-water free-surface simulation that I do often.
I use a lot the impulsive start method because I find it more straightforward to setup and I was tempted to use implicit relaxation in the free-surface equation to calm it down especially during the first time-steps.
That turned out not to be a good idea at all as it was causing divergence of my simulations…
So now, I stick to values around 0.9 – 0.95 !
