Show HN: 3D Ising Model Simulation – interactive web-based Monte Carlo simulator

Based, 3D Ising Model Simulation – interactive web-based Monte Carlo simulator works in show hn launch.

Profile

Hello HN! I’ve just released an interactive 3D Ising model simulator built with Next.js. It’s a teaching/demo tool for exploring phase transitions and critical phenomena in ferromagnets.## Key Features- Real-time 3D visualization: See a central 2D slice through a 32×32×32 periodic lattice- Adjustable parameters: Sweep the dimensionless coupling strength (βJ = J/kBT) through the critical point (≈0.22) and tune the external field (βh = h/kBT)- Monte Carlo updates: Uses the Metropolis algorithm, updating the display every 200 × N³ flip attempts (≈33 million total)- Live observables: Watch energy and magnetization evolve as you change parameters## Why this matters The Ising model is a cornerston

As a business in show hn launch, 3D Ising Model Simulation – interactive web-based Monte Carlo simulator is listed here with the public details available about it.

Directory data places it at the Show HN launch stage.
