NovaSolver — Interactive Physics & Engineering Simulators

1600+ interactive simulators covering structural mechanics, fluid dynamics, heat transfer, electromagnetics, and more. All run entirely in your browser with no installation, no signup, and no server-side computation.

What is this?

NovaSolver provides browser-based simulators for engineers, students, and researchers learning CAE (Computer-Aided Engineering) and physics. Each tool implements a well-known equation or model — Euler-Bernoulli beam, Reynolds number, Lissajous figures, RC/RL transients, FFT spectrum, Mohr's circle, and 1600+ more — with real-time visualization driven by sliders.

The mission: make every closed-form result in classical engineering interactive, so the path from "I read the equation" → "I see how parameters change the answer" takes 5 seconds, not a Matlab session.

Categories

Category	Count	Examples
Structural mechanics	360+	beam deflection, buckling, fatigue (Goodman, Paris), Mohr's circle
Fluid dynamics	330+	Reynolds, Bernoulli, flow around cylinder, potential flow
Heat transfer	240+	2D heat diffusion, fin efficiency, Stefan-Boltzmann
Electromagnetics	280+	RC/RL circuits, Bode plots, antenna gain, FDTD
Coupled multi-physics	240+	thermal-structural, electrochemical
Physics & math fun	100+	Lissajous, Lorenz attractor, boids, double pendulum chaos

Architecture

• Pure static HTML + Vanilla JS (no React/Vue). Renders to canvas + Chart.js.
• MathJax for LaTeX equations.
• No backend for simulation — everything client-side.
• Multilingual: JA / EN / ZH-Hans versions of every page.
• i18n: hreflang properly set; canonical / OG / structured data per language.

Each tool folder is self-contained: drop it on any static host and it runs.

Quick start
