Looking for someone to test out the program I wrote. Try to follow documentation and play around with the simulation. Any suggestions are welcome.

@Oscilous I would like to test your project; I just want to confirm if you will be okay with me creating a test folder.

Alright, I will let you know my thoughts later today!

I have tested the simulation and it works really well. It is responsive and the pixels mirror real-life physics.

One thing I noticed is that the water does not displace the sand particles when it pushes against it. For instance when there is a small lump of sand and a lot of water, ideally, the pressure of the water should be enough to flatten the sand, but in the simulator, the sand is still intact as though it can withstand the pressure of the water.

I have added a photo to illustrate. In the screenshot, the small lump of sand should have been flattened by the water.

Thank you for your response, I really appreciate you taking some time to check this out. You have made a great point. I didn't take into account pressure. I thought the water would not prevent the sand from pilling up under water, like currently. So if I understand correctly, the sand should try to be as flat as possible due to the water pushing down on it? Additionally, what if the water surface is not fully flat, would the sand be lower, where there is more water above it, due to pressure?

The way I see it, it depends on if the water is flowing towards the sand or it is just on top of the sand. It is flowing towards the sand, the pressure should displace the sand and make it flat.

If the water is static, then ideally it should not displace the sand.
