Orthogonal is a modern, browser-based software platform for advanced numerical modelling and computing that uses AI to make complex workflows faster and smarter. It is based on the open Modelica language. It runs entirely in your browser, so you don’t need to install anything, and is ideal for sytsem modelling, control, optimization, and simulation tasks. Orthogonal is particularly useful for structured numerical algorithms, large-scale problems, and AI-assisted analysis.
