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 approach that we have developed to address them within CSDMS.

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