Towards computer-aided multiscale modelling: An overarching methodology and support of conceptual modelling

Multiscale modelling is now widely regarded as a promising and powerful tool in various disciplines, including the broad area of process engineering. However, a multiscale model is usually much more difficult to develop than a single-scale model due to a range of conceptual, numerical, and software challenges. Currently, there is little support developed to facilitate multiscale modelling. This paper discusses the key challenges faced by computer-aided multiscale modelling (CAMM) and presents a methodology for developing a computer-based, generic and open supporting framework for multiscale modelling. Details are particularly provided on the development of a conceptual modelling tool, an important element of the envisaged tool set for CAMM. The application of this tool is illustrated by two reactor modelling examples.

• We summarize the key challenges faced by computer-aided multiscale modelling (CAMM).
• We propose a methodology for developing a generic framework for CAMM.
• We develop a conceptual modelling tool for CAMM.
• The application of this tool is illustrated by the modelling of two reactor systems.
