Abstract
Multiscale modelling as an emerging modelling paradigm is now widely regarded as a promising and powerful tool in various disciplines. However, a multiscale model is usually much more difficult to develop than a single-scale model due to a range of challenges. This work presents a methodology to facilitate the development of multiscale models, which comprises three main modelling steps, namely conceptual modelling, model realization and model execution. A set of proof-of-concept tools have been developed to realize the proposed methodology. A case study on the modelling of a heterogeneous chemical reactor is presented to demonstrate these tools and to illustrate the key concepts. © ECMS.
