Research Group MicroSystems Simulation

The working group for microsystem simulation was founded in April 2017. Their research interests are the multi-physical modeling of micro- and mechatronic systems as well as their simulation on system level. Mathematical methods of model and reduction and topology optimization are applied.

Research interests

  • Modeling and simulation techniques for multi-physical micro-mechatronic systems
  • Model or reduction for time-efficient system simulation
  • Topology optimization

Due to its nature as an energy converter, the coupling of multiple energy domains is an inherent feature of many microsystems. Their modeling at the continuum level and the numerical simulation of individual components is regarded as state of the art. However, as soon as a co-operation of the component with the surrounding electronics, the housing or other components is to be considered, more compact models with acceptable accuracy are necessary.

A reduced model is obtained by mathematical reduction of the number of degrees of freedom of a numerical model. The main advantage of a mathematical model or reduction (MOR) is its automatability and high accuracy. Our MOR methods can be applied directly to large differential equations systems, which arise, for example, in the Finite Element Method (FEM). Reduced multiphysical models can be solved in a time-efficient manner and can be used as a part of an optimization.
