Learn engineering
through simulation
Interactive 3D simulations for every semester, every subject. Built on Three.js — no plugins, no downloads, runs in your browser.
Why Simatrix?
The gap between theory and intuition — closed with simulation.
Interactive 3D
Rotate, zoom, change parameters in real time. Not videos — actual simulations you can manipulate.
BTech-aligned
Every simulation maps to a specific subject and semester. Nothing irrelevant, nothing out-of-syllabus.
All 8 semesters
Semester 1 through 8 across all major engineering branches — Physics, Circuits, Mechanics, and more.
