Although being highly successful in individual engineering domains, these systems face new challenges with the growing demand for integrated modelling and simulation of highly complex, multi-disciplinary technical systems.
Substantial problems result from lacking openness and interoperability of simulation environments.
As a consequence there exists an additional modellevel on top of the usual software level, with strong parallels, but also differences between both levels. A second, complementary goal of our work is interoperability among generic simulation systems on model level . With this extension, Smile can serve as an integration platform also w.r.t model components imported from other simulation environments. The Smile simulation environment is being used in a variety of projects, mostly in the field of energy engineering. Large parts of the Smile system where rewritten to achieve more openness and extensibility and to react to user feedback.
