discretize

discretize - A python package for finite volume discretization.

The vision is to create a package for finite volume simulation with a focus on large scale inverse problems. This package has the following features:

• modular with respect to the spacial discretization
• built with the inverse problem in mind
• supports 1D, 2D and 3D problems
• access to sparse matrix operators
• access to derivatives to mesh variables

Currently, discretize supports:

• Tensor Meshes (1D, 2D and 3D)
• Cylindrically Symmetric Meshes
• QuadTree and OcTree Meshes (2D and 3D)
• Logically Rectangular Meshes (2D and 3D)
• Triangular (2D) and Tetrahedral (3D) Meshes

Installing

discretize is on conda-forge, and is the recommended installation method.

conda install -c conda-forge discretize

Prebuilt wheels of discretize are on pypi for most platforms

pip install discretize

To install from source, note this requires a c++ compiler supporting the c++17 standard.

git clone https://github.com/simpeg/discretize.git
cd discretize
pip install .
