The record

Purpose: PyMPDATA is a Numba-accelerated Python implementation of MPDATA for numerically solving generalized convection-diffusion and transport equations.
Dimensions: It supports integration on structured meshes in 1D, 2D, and 3D, with optional coordinate transformations.
Algorithm options: Supported MPDATA variants include non-oscillatory, infinite-gauge, divergent-flow, double-pass donor cell, and third-order-terms options.
Diffusion: It supports Fickian terms in advection-diffusion problems through a pseudo-transport-velocity approach.
Parallelism: 2D and 3D simulations use domain decomposition for multithreaded parallelism; a separate PyMPDATA-MPI project demonstrates distributed-memory parallelism.
Installation: The package is available on PyPI and can be installed with pip; the documentation says user installation does not require a compilation stage.
Supported operating systems: The documentation lists Linux, OSX, and Windows among the platforms supported for installation.
Dependencies: PyMPDATA depends on NumPy, Numba, and pystrict.
Boundary conditions: The library provides Periodic, Extrapolated, Constant, and Polar boundary conditions.
Examples: A separate PyMPDATA-examples package provides usage examples, and its notebooks can be run through Google Colab or mybinder.org.
License: PyMPDATA and PyMPDATA-examples are free/libre open-source packages released under the GNU GPL v3 license.
Support: The maintainers recommend GitHub Discussions for help understanding, using, and extending the code, and the GitHub issue tracker for reporting incorrect, unintuitive, or undocumented behavior.
Notable limitation: Installing PyMPDATA alone does not install the separate examples or MPI packages.
Intended users: The project describes its design as serving research users, developers, and maintainers.
