Open-source, implicit 3D structural geological modeling in Python.

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

as it will take care of automatically installing all the required dependencies - except in windows that requires one extra step.

Windows does not have a gcc compilers pre-installed. The easiest way to get a theano compatible compiler is by using the theano conda installation. Therefore the process would be the following:

$ conda install theano

$ pip install gempy

For more information, refer to the installation documentation.

Resources

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

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

For questions and support, please use discussions.

If you find a bug or have a feature request, create an issue.
