Show HN: 2D Coulomb Gas Simulator
swesnow Monday, February 16, 2026A pretty simple but fun to play with simulator for a concept from mathematical physics called the "2D Coulomb gas". I originally made this for my Bachelor's thesis to create pretty pictures and build intuition but have recently gotten it a fresh coat of paint and better performance curtesy of WebGPU acceleration (ported with liberal help from Codex to get through all of the boilerplate).
Play around with it - hopefully read up more on the 2D Coulomb gas because it is an incredibly deep topic research wise.
Summary
This website provides a 2D Coulomb Gas Tools application, allowing users to simulate and visualize the behavior of a 2D Coulomb gas using GPU acceleration. The tool enables interactive exploration of various parameters and their effects on the Coulomb gas dynamics.
