OpenGeoRock
v0.1.6 · in active development · GPL-3.0

Open-source geotechnical
software, built in the open.

OpenGeoRock is a growing suite of Python programs for slope stability, rock mechanics and finite-element geotechnical analysis — designed as a rigorous, modern alternative that engineers and researchers can read, extend and trust.

01 / The project

A modern, transparent toolkit for ground engineering.

OpenGeoRock is a community-driven suite of geotechnical analysis programs, written entirely in Python and released under GPL-3.0 so anyone can read the source, reproduce results, and extend the engines.

Most of the software geotechnical engineers rely on is closed, expensive, and opaque — a black box at the centre of decisions about dams, slopes, tunnels and foundations. OpenGeoRock is an effort to rebuild those core tools in the open, with a clean engineering core, a modern desktop interface, and a test suite that anyone can inspect.

The suite will grow incrementally. We are starting with 2D slope stability — the tool practitioners reach for most — and will expand into material databases, 2D/3D finite element analysis, and 3D limit equilibrium over the coming years.

Design principles
01
Readable engines
Computation cores are pure Python, documented, and decoupled from the UI so they can be scripted or embedded.
02
Modern desktop UX
A clean PySide6/Qt6 interface with a proper modeller, interpreter, and an embedded Python terminal for automation.
03
Verifiable results
Benchmarks and reference cases ship with the source. Any run can be reproduced from its project file alone.
04
Built for contribution
Small, well-scoped modules. New methods, materials and analysis types are meant to be added by the community.
02 / First release
OGR Slip2D / ogr-slip2d

A modern, open-source 2D slope stability program based on the Limit Equilibrium Method. It supports circular and non-circular failure surfaces, multiple materials, pore pressure models, external loads, structural reinforcement, and seismic analysis.

03 / The suite

Five programs, one open ecosystem.

OGR Slip2D is the first piece. Over the coming years the suite will grow to cover the workflows a modern geotechnical office runs daily — from material databases to 3D finite element analysis.
01
OGR Slip2D2D slope stability
Limit-equilibrium slope stability in 2D. Circular and non-circular surfaces, staged loading, pore pressure models, reinforcement and pseudo-static seismic analysis.
In development
02
OGR Datamaterial & rock-mass database
A curated, queryable database of soil and rock-mass properties, correlations and empirical charts, feeding the rest of the suite with consistent inputs.
Planned
03
OGR FEM2D2D finite element analysis
Elasto-plastic 2D FEM for stresses, deformations and strength reduction, for excavations, tunnels and embankments.
Planned
04
OGR Slip3D3D slope stability
Extension of the limit-equilibrium engine to fully three-dimensional failure surfaces — for open-pit mines, landslides and complex terrain.
Planned
05
OGR FEM3D3D finite element analysis
Full 3D finite-element solver for rock and soil mechanics: stress analysis, deformation, and coupled groundwater flow on arbitrary geometries.
