For a similar simulation but using a different method, you can find one here[0]. It obviously lacks the force control, but has the viscosity tunable parameter.

Re: Water
#132While very cool, what's not realistic is the liquid coming to a rest. Even 5+ minutes after resting my phone against the wall (to ensure no vibrations), there were still sizable currents.
I thought the same thing when looking at the ocean the other day. I found it very unrealistic that it was still moving about after all this time.
I thought the same thing when looking at my pool the other day. I found it very realistic that the water was still after no movement in it after a period of time.

#133My dad worked on the Apollo program In The 60s. They were using analog computers to simulate fuel slosh in the tanks. He also had a flight sim display that allegedly could go from space (earth as a circle?) To low level horizon and grid. I never saw either but am about to toss schematics for the later with the rest of his stuff. Personal note - he died in '03 and I'm done hanging on to stuff. :-)
I sent you an email -- happy to help (virtually) with finding a good home for these. Cleaning out a lost relative's possessions can be hard. I think a lot of other people here might be able to help in some ways too.
Re: Water
#134Very cool, beautiful. I did a kids toy kind of thing like this using Unity for Android taking input from the handheld's accelerometer to make a sphere (ball) roll around (according to how the handheld device is tilted) and bump into targets.
As regards to "the water should eventually stand still" I found the accelerometer input to be sooo sensitive that even when you placed the handheld on a level surface (sussed out with a carpenter level) the sphere would slow down a lot but never stop moving.
A glass of water placed on a table eventually stops moving - according to our senses. But does it really?

Re: Water
#136I always took water for granted. In my country where I grew up, we had water available to us in the sink 24/7, 365. Pure, clean. Drinkable. As I am now traveling the world, I am experiencing places where water is not to be taken for granted. But only in mild ways. Not in actual life-or-death ways. That happens in countries I have not yet visited. It’s weird. Most of my time at work I deal with pretty mundane things.…
This makes no sense.

#137I opened it on my laptop, which doesn't have any motion sensitive device on it. Where does the left-right asymmetry arise from?
The universe actually has a very slight tilt.

My point is that we don’t know the forces that the simulation is intending to model. There may be water flowing in/out along the z-axis, for example. Or there could be wind. Assuming that the author intended to simulate the same conditions in your pool, and then criticising them for not modelling it accurately enough, makes no sense to me.

#139crashes on firefox
does not crash on firefox (More seriously - you need to provide more information. On Windows 10, Firefox 116.0.1, it does not crash. But it's a laptop so there's no device motion.)
