Mimpy is a Python based library for solving the diffusion equation. Mimpy uses the Mimetic Finite Difference method, which as the advantage of solving using general polyhedral elements.
Because diffusion is a "kernel" for many physical phenomena, mimpy can also solve problems like the heat equation and multi-phase flow through porous media.
A simple example can be found in hexmesh_example_1.py. Run:
$ python hexmesh_example_1.py
Code requirements:
- NumPy
- SciPy
- Cython (if you want to update the c code).
