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
