Introduction
The Basic Model Interface (BMI) is a set of standard control and query functions that, when added to a model code, make that model both easier to learn and easier to couple with other software elements. Detailed information about BMI can be found at https://bmi.readthedocs.io.
Classroom organization
In this lab, we explore what BMI is and how to use it through a pair of Jupyter Notebooks. This lab first illustrates an example "Heat" model which simulates the diffusion of temperature on a uniform rectangular plate with Dirichlet boundary conditions. Then, the lab demonstrates how to run the "Heat" model through its BMI.

Lab notes
This lab can be run on the CSDMS JupyterHub. (If you don't already have an account, follow the instructions to sign up at: https://csdms.colorado.edu/wiki/JupyterHub.) Run the lab Notebook by clicking the "start" link under the Run online heading at the top of this page. If you're an educator using this lab in a class, you can get CSDMS JupyterHub accounts for students. For more information, please contact us through the CSDMS Help Desk: https://github.com/csdms/help-desk.
Requirements
If run locally, this lab requires the source code from the bmi-example-python repository: https://github.com/csdms/bmi-example-python.
