Basic Model Interface (BMI)

Version 2.0

Automobiles benefit from a standard interface. Regardless of whether you drive a pickup truck or an electric two-seater, you use an ignition, an accelerator, and steering wheel. Imagine having to spend weeks of study to switch from one type of automobile to another, or from one brand to another. At CSDMS, we believe that numerical models, and the sub-components that make up these models, should offer a similar kind of standardization. To this end, we have developed the Basic Model Interface (BMI): a set of standard query and control functions that, when added to a model code, make that model both easier to learn and easier to couple with other software.

BMI is an element of the CSDMS Workbench, an integrated system of software tools, technologies, and standards for building and coupling models.

 '''Version 2.0'''
-Development of scientific modeling software increasingly requires the coupling of multiple, independently developed models. Component-based software engineering enables the integration of plug-and-play components, but significant additional challenges must be addressed in any specific domain in order to produce a usable development and simulation environment that also encourages contributions and adoption by entire communities. In the documents linked below,  we describe the challenges in creating a coupling environment for Earth-surface process modeling and the innovative approaches that we have developed to address them within CSDMS.
