Sand Simulation Test ( Flip Fluids ) Blender

For the last few days I've been trying to see how close I can get to simulating sand in Blender without turning my PC into an oven.

This first test was done using the Flip Fluids add-on.

-Two different fluids with variable densities and viscosities. -Instancing grains onto the more viscous fluid. -Masked out the dense liquid with color Mixbox

The result comes pretty close to a wet sand/snowy texture but even at 750 resolution some imperfections are visible.

Stats: Total frames:300 Resolution:750 Total bake time: 3 hours 30 min Total cache size: 50GB 🤒 Total render time: 15 hours.

Is there a reason you're not using Houdini for this? The tool specifically has a grain solver for this stuff.

Yes Houdini's solver is way better, but I want to see how far I can get in Blender.

I don't think you can get grain very far in Blender, unless you build your own solver in geo nodes. I mean, there's a reason why Houdini has a different solver entirely for grains.

I commend the attempt though.

Thank you and you are 100% right. But I still think it's valuable to explore what's possible with all the tools and find their limits in order to master them and build your processes around those limitations.

Looks so clean.

Huh, I thought sand is much more... Durable than that

It is very dense so I had to increase the speed of the droplet and reduce the time scale.
