Parallel Co-Simulation for Mechatronic Systems

The simulation of physical systems is a very important task in modern product development. Besides single domain systems also the simulation of multi domain systems as a whole has increasing importance. This work deals with coupled simulation of multi domains, especially mechanical, hydraulic and electric ones, using co-simulation: the subsystems are integrated by their own integrators and are dynamically connected at discrete macro time steps. The main aspect lies on stability improvements and parallelization to achieve time efficient simulations on multi CPU computers. Beside analytical considerations also examples of industrial relevance are given showing the power of parallel multi domain co-simulations.
