Documentation
Everything you need to go from a blank canvas to a fully solved, unit-correct, uncertainty-aware simulation. Start with the guides, then dive into the node reference.
Guides
Introduction
Getting started
Install Captyse, open your first project, and wire your first node graph.
Introduction
Node-based programming
How the dataflow graph works: sources, transforms, sinks, and compounds.
Core concepts
Units & uncertainty
The two pillars: native physical units and ±σ measurement uncertainty, end to end.
Core concepts
The simulation engine
Turn a cyclic feedback graph into a solved ODE system with 11 solvers and events.
Guides
Export & LaTeX figures
Publication-grade export: true vector SVG/PDF and native TikZ/LaTeX.
