gempy 2025.2.0

An Open-source, Python-based 3-D structural geological modeling software.

What's New: GemPy 2024.1 (a.k.a GemPy v3) Release!

Welcome to the era of GemPy v3! We are thrilled to announce the release of the latest version, a product of meticulous planning, redesign, and rigorous testing. While the core essence remains intact, v3 brings significant enhancements and novelties that promise to revolutionize your geomodeling experience.

Delve into the exciting new features in the What's New in GemPy v3.

The journey from GemPy v2 to v3 has been transformative. To ensure that our users don't lose out on any previous functionalities, we've shifted v2 to a package named gempy_legacy. While the core team will not develop any new features for this version, we'll continue maintaining it based on community requests.

Overview

GemPy is a Python-based, open-source geomodeling library. It is capable of constructing complex 3D geological models of folded structures, fault networks and unconformities, based on the underlying powerful implicit representation approach.

Installation

We provide the latest release version of GemPy via PyPi package services. We highly recommend using PyPi,

$ pip install gempy[base]

Resources

After installation, you can either check the notebook tutorials or the video introduction to get started.

Go to the documentation site for further information and enjoy the tutorials and examples.
