Start with a cube and attach a "Collider" tag with the following settings – high "Friction" prevents the particles from spreading out, a low "Bounce" value avoids "elastic" particles:
- Add a "Sphere" emitter. Enable "Fill sphere", set "Speed" to 0, and "Randomness" to 0.2.
- Go to Fluid > Fluid, and enter 100 for "Resolution" and 2 for "Surface Tension",
- Create a "Gravity" daemon.
- Next, create a "Drag" daemon and animate its "Drag Strength" from 0 to 400.0 between frame 0 and 200. This helps to slow down the fluid and make it rest.
- Simulate for 250 - 300 frames.
