Discussions and questions regarding the modelling processes itself, including different modelling paradigms, algorithms, integration of model and data (calibration, validation) how to model specific processes and examples of models that the community may find interesting.
Discussions about modelling and models may of course include references to specific software implementations, but questions that are software-specific (e.g., error messages, feature requests, installation issues) should be better discuss in the Software category.
Also, if you want to present some application of a model the Use Case category may be a better place as discussions tend to be less technical when discussing case studies and applications.
