ropesim 3.0.4 — 2026-07-08

Climbing rope physics engine — Python library, CLI, TUI, and a native 3D desktop app.

ropesim models lead-fall dynamics with a UIAA 101 / EN 892 impact-force model and
RK4 damped-spring integration in a Rust core (optional Rapier3D full-physics mode).
One engine, four frontends: a pip-installable Python library, a 20+ command CLI, a
Textual terminal UI, and a native C++ / Qt6 desktop application with a 60 fps OpenGL
rope renderer.

Added

  • Example script examples/demo_2d.py: runs a full analytical fall and plots six figures (force curve, belay-device comparison, energy budget, rope elongation, route position sweep, and route schematic)
  • Example script examples/demo_3d.py: runs a Rapier 3-D fall and plots the rope in 3-D at peak load, the climber's fall path, and the anchor force curve
  • Desktop GUI Demo menu — 2D Fall Analysis Demo (F9) and 3D Rapier Fall Demo (F10) preset a complete lead-fall scenario, switch to the matching view, and run the simulation with no setup required

Install

Python library / CLI / TUI (all platforms, Python 3.10–3.12):

pip install ropesim          # library + CLI
pip install "ropesim[tui]"   # + terminal UI

Desktop app (no Python required) — download an asset below and run:

  • Windows — unzip ropesim-gui-windows-x64.zip, run ropesim-gui.exe
  • macOS — open ropesim-gui-macos.dmg (unsigned: right-click → Open the first time)
  • Linux — chmod +x ropesim-gui-linux-x86_64.AppImage && ./ropesim-gui-linux-x86_64.AppImage

⚠️ ropesim informs judgement — it is for education and planning, never a substitute for testing, redundancy, and experience at the crag.
