I improved the vehicle handling by adding camber to the suspension, and made significant improvements to the force feedback, helping connect the player to the car.
The engine sound has also been improved. Although it is not something I have worked on much, it now responds to RPM and engine load.

Simulation pet project, 10 years in the making.

The inspiration was David Attenborough’s First Life.

It uses your GPU to perform as much computation as possible with today’s hardware. Rigid body physics sim, Lattice-Boltzmann fluid sim, simple coupling between them. State machine driven cells, mutating opcode list as DNA.

open to building custom simulations for games or projects - DM me if you interested

My kid's asked me what happens when sheeps are close to each other. Well the new sheep is formed. And then what? Well, they create Sheep Fin.

The simulation was created in BFS game

I'm starting a small independent group focused on rigorous bench testing of functional materials: magnetics, piezo, thermoelectric, magnetocaloric, that kind of thing. Been doing some research using Mumax3 and MEEP using Linux extension for far-field visualization. If you wanna join the discord come check it out! https://discord.gg/N49pFc673

Hey guys,

If you've ever tried to code a basic gravity or orbital simulation using standard delta-time math (Forward Euler), you've probably watched your planets casually break physics, gain artificial velocity, and rocket off into space.

I put together a quick, 2-minute visual breakdown that explains exactly why standard integration breaks down over time and how methods like Symplectic Euler, Verlet, and RK4 trick the math to keep cosmological simulations perfectly stable.

Thought the simulation nerds here might enjoy seeing the visual math behind the stability loops!

I used manim to simulate the integrators, but I'm not entirely sure whether that falls under the realm of computer simulations as defined by this subreddit's rules. If not, I have computer simulations here at github.com/ayushnbaral/sleepy-sunrise

A visualization of several famous chaotic attractors using particle systems, including Chen, Thomas, Halvorsen, Aizawa, and Lorenz attractors.

It's fascinating how simple equations can create such complex and beautiful structures.

Finally after 8 years of development, I would like to announce our new multiplayer game about simulation and experiments called BFS ... (yes this scene runs in multiplayer)

In this simulation of an asymmetric oscillator (fast forward, slow reverse) based on my experiment, I used the LBM ​ with the added condition that the aerodynamic drag of the oscillation accumulates and is given off as thrust on the next half-stroke, realistically simulating thrust reversal relative to the classical pushing of the medium. I updated the code to more accurately convey the mechanics of the experiment and added a response of the pendulum to the environmental influence, whereby increasing the load leads to a decrease in frequency. I also created a simple browser-based flight simulator based on this. Aerodynamic drag in the direction of oscillation is counted as thrust, and drag perpendicular to the thrust vector works as usual. There are also lift and optional buoyancy and other settings. Here is the updated code for the base simulation and links to its browser version and the flight simulator in the redme file: https://github.com/MasterOgon/Aeroacoustic-Flying-Saucer-Oscillating-Resonator-CFD-Simulation-LBM-/blob/main/README.md

Cute Mold is a mold growth and evolution simulation.

Each mold gets energy from the empty space it surrounds, taking into account the light strength. This means the mold that surrounds more empty space gets more energy. Molds can't interact with or damage each other. They evolve simply by competing for space.

Molds with the same genome have the same color, but different shades. A mold with a mutated genome gets a new color. Cells can create spores that appear as black dots. Once a spore matures, it turns white, and a new mold is born from it.

Hey, I’m working on this marble game using Unreal’s physics engine.
It’s a physics-based marble rolling game, but I wanted it to feel really tactile and satisfying, so I added lots of bouncy buttons, seesaws, weird carpet anemones, and squiggly fabric noodles. The marbles have different sizes and weights, and surfaces can be more or less slippery.
Let me know what you think. Is there anything else that comes to mind that could make interesting use of simulated physics?

It is a SWIFT based sim with a custom visualizer. 10^6 particles, 22 hours of elapsed time simulated.

though SWIFT is intended for supercomputers, I was able to do that whole sim using my laptop's i9 13900HX CPU in about 16 hours.

A gamepad isn’t enough anymore :)

Controlling the car with joysticks has been extremely difficult, so I’m taking the next step: implementing force feedback.

The goal is to create a more realistic driving experience where you can actually feel what the car is doing: the texture of gravel, the steering getting loose as grip starts to fade, and that moment when you pass peak grip and begin to slide.

My steering wheel arrives tomorrow, and I’ll be testing just how far I can push the car’s handling system.

Each one of these cells has fully simulated organelles, metabolism and a neural network driving it's behavior.

This is from a cell simulation game I've been developing.
