This application allows the calibration and simulation of dynamic models, following the step-by-step guide described in:

Dafermos Y. and Nikolaidi, M. (2026). Ecological stock-flow consistent modelling: a theoretical and practical guide, in S., D’Alessandro, T., Distefano and G., Morlin (eds.), Open Book Publishers, forthcoming

The app uses the DEFINE-SIMPLE model by default. However, this can be replaced by any other model either manually or by using the R code of DEFINE models that have been derived using the app.
