This is how the planets and moons move relative to the solar system barycenter. In a similar way the whole solar system moves around the center of the milky way.

FluidX3D is a GPU-accelerated real time 3D fluid simulation based on the lattice Boltzmann method.
Ive added some upgrades, namely the one-step-pull algorithm (OS-Pull) for a combined streaming-and-collide step which cuts VRAM access in half.
Particles are also calculated on the GPU. They dont impact performance much (less than 1%), since 65536 is a small number compared to 256x128x128 LBM nodes. Furthermore, if only the particle positions have to be sent over PCI-e to the CPU for graphics instead of the entire velocity field, it doubles the calculation steps per second, because then the GPU does not have to wait idle until the slow data transfer is done.

FluidX3D is a GPU-accelerated real time 3D fluid simulation based on the lattice Boltzmann method.
Ive added arbitrary boundaries. This enables setting arbitrarily shaped walls inside the simulation box and observing the fluid flow around them.
The simulations in this video are sped up by 2x because the simulation box is quite large at 128x128x256. Keep in mind that the simulations run on a Laptop from the year 2015.

The Ulysses spacecraft was launched in 1990 to study the Sun from an orbit far off the ecliptic plane. It reached its orbit in 1992 using a slingshot maneuver on Jupiter which left its apoapsis crossing Jupiters orbit.
On November 4th 2098 it will get close to Jupiter again and do another slingshot maneuver which will raise its apoapsis beyond the orbit of Neptune.
The simulation is performed in real time on a notebook CPU based on data from the JPL. FP64 percision and RK4 integration with adaptive timestepping are being used.
