An example of implementing the Python bindings for the CSDMS Basic Model Interface (BMI).

This is an example of implementing a BMI for a simple model that solves the diffusion equation on a uniform rectangular plate with Dirichlet boundary conditions. The model and its BMI are written in Python 3. Tests of the BMI are provided.

This repository is organized with the following directories:

heat

Source code for the model and its BMI

examples

Jupyter Notebooks that demonstrate how to run the model through its BMI

tests

Tests that cover the BMI of the model

This example can be built and installed on Linux, macOS, and Windows.

Prerequisites:

• Python 3
• The Python BMI bindings. Follow the build and install directions given in the README in that repository. You can choose to install them from source, or through pip or conda.

To build/install this example from source, using the current Python BMI version, run

$ pip install -e .

To run the tests,

$ pip install -r requirements-testing.txt
$ make test
