This simulation was originally designed for fluid dynamics and is based on the concept of a vortex as a coordinated Brownian motion. This was necessary for the theory of motion of asymmetrically oscillating bodies with which I was experimenting https://www.reddit.com/r/AerospaceEngineering/comments/1sn9cu2/my\_experiment\_with\_a\_vibro\_plane\_initially\_i/?utm\_source=share&utm\_medium=web3x&utm\_name=web3xcss&utm\_term=1&utm\_content=share\_button
Therefore, in astrophysics this can be used for dust and gas. Although the flexibility of settings allows you to make a regular N-body.
Composite radial force ombines gravity-like 1/r^2 attraction with short-range repulsion to pervent collapse.
Active spin gives tangential force vector t_{vec} applied perpendicular to the radial vector. This induces orbital rotation and collective swirling behavior.
Spin is suppressed by density, allowing nuclei to form.
Optional particle oscillations to enhance elastic collisions to simulate temperature.
In the simulations in the video, all values are chosen arbitrarily by eye. For now this is just a visualization, but I think it could become a precise tool and I'm interested in how this could be done. For example, to simulate specific environments or find a balance of forces to see the full picture.
There are several options for customizing the source code here: https://github.com/MasterOgon/Newtonian-Superfluid-Simulation The hints in the code can be confusing, it has been changed many times.
And you will also find an online open-source application there that you can test. I would appreciate any feedback.
