The SSG is developed upon the same ontology of general multiscale systems as used by the conceptual modelling tool developed earlier ( Zhao et al., 2010). To support the latter mode of model realization, a simulation script generator (SSG) is developed in this work, which facilitates a modeller in constructing a multiscale simulation based on the combination of several existing single-scale modelling tools, such as gPROMS, Fluent and Aspen Plus. However, the applicability of this approach is limited given the fact that, in contrast to building a model completely from scratch, a more realistic mode of multiscale simulation is by the integration of existing modelling tools, each simulating one particular scale of a multiscale system. This approach would result in a “single” set of equations that can be solved collectively to realize a multiscale simulation. The essence of this approach is that a mathematical model is composed by selecting and customizing elements from a library of basic building blocks according to the conceptual model.

Starting with a conceptual model, it is envisaged that a multiscale model may be realized by automatic code generation, following an approach similar to the one proposed by Yang et al.
