M2modeller

M2modeller is a cross-domain modeling framework designed to facilitate the construction, simulation, and analysis of mathematical models by assembling reusable components. It emphasizes Model-to-Model (M2M) integration, enabling users to connect independently developed models into larger systems without rewriting code. The platform provides both a graphical interface for composing models and a scripting API for automation, with core execution implemented in a high-performance language and bindings for Python.

Key features include a component-based modeling approach, a simulation engine capable of discrete-event or continuous-time dynamics, and support for parameter sweeps, sensitivity analysis, and optimization workflows. It offers built-in validation tools and can import and export common data formats such as CSV and JSON. Interoperability is supported through adapters that connect external models to the framework, while a model repository enables sharing components and templates. Project files help ensure reproducible experiments and analyses.

Typical applications span life sciences, engineering, environmental and social systems, education, and research. Users construct models by selecting components (such as processes, compartments, or agents), defining interfaces, configuring parameters, and running simulations to study system behavior under varied conditions.

The architecture comprises a component library, a model assembler, an execution engine, data I/O and visualization modules, and collaboration features for versioning and sharing. While the system aims to be accessible to scientists and engineers, effective use generally requires familiarity with modeling concepts and software workflows.

M2modeller is maintained as an open-source project with contributions from an international community. Documentation and community resources are provided on the official site and repository. Limitations include a learning curve for new users and performance considerations for very large-scale models.
