The numerical simulation of coupled problems deals with the numerical treatment of interactions of different physical phenomena (coupling of fluid mechanics, structural mechanics, heat conduction, optics, electromagnetism, and so on) and with interactions of such physical effects with the behaviour of a higher system (a circuit, a hydraulic network, or a design process, e.g.). Especially for the simulation of micro-miniaturized components, it has turned out that it is essential to take into account such couplings.
For the realization of the numerical simulation of coupled problems, we study a modular approach, where solvers for the different sub-problems can be combined by an outer iteration scheme to an overall solver for the coupled problem, or where simulators for the different components of a system can be integrated into an existing system simulator, resp. In this context, our applications cover structure-structure-, fluid-structure-, and acoustics-structure interactions. Concerning fluid-structure-interactions, problems coming from microsystem technology like the three-dimensional simulation of a valve-driven micropump are in the centre of interest.
