From August 19 to 22, 2025, RTG doctroral student Christian Gutsche (project F4) and his supervisor Prof. Uwe Aßmann from the Chair of Software Technology went on a research trip to Linköping in Sweden. The development of the equation-based modeling language Modelica is being driven forward at Linköping University.
Modelica and other equation-based modeling languages are used to model complex technical systems with physical differential equation systems. The modeled system is simulated by solving the systems of equations. Such simulations can be used to gain a better insight into the functioning of technical systems. This is essential for energy systems of the future, which will have to change their behavior in a highly dynamic way to ensure that they function as sustainably as possible. Computer science refers to this as self-adaptive systems. The further development of equation-based modeling languages and the simpler simulation of self-adaptive systems are the focus of doctoral projects F4 and F6 of the Boysen-TUD- Research Training Group.
The days in Sweden were used to exchange ideas with researchers at PELAB, the research facility where Modelica development is being driven forward. Here, doctoral student Christian Gutsche presented his work and outlined the advantages of the approach. In addition, limitations of Modelica were discussed, which complicate the development of simulations for self-adaptive systems. The numerous relevant discussions also highlighted potential opportunities for cooperation, which are now being worked on intensively.
The research trip was a valuable experience with great impressions of the lively campus of Linköping University. The helpful feedback from the experts in Linköping will make a positive contribution to Christian Gutsche's doctorate.
