Particle based simulation methods are an attractive approach to discretise nature in order to perform computer simulations. By adapting the particle interactions to the specific needs of a given physical problem, particle methods may be used on any scale where classical Newtonian mechanics is valid. In this work use is made of the natural representation of large deformations, free surfaces and convection for the simulation of micro powder injection moulding with the smoothed particle hydrodynamics method (SPH). This simulation method allows to reproduce experimentally observed unexpected filling patterns and the demixing of embedded powder particles. On the mesoscale, the dissipative particle dynamics method (DPD) includes thermal fluctuations but ignores all the molecular detail. For fluid dynamics on this scale an efficient energy conserving model is presented which allows to simulate non-isothermal liquids with phase transitions such as the Van der Waals gas. DPD was also applied to the molecular coarse-graining of carbon nanotubes. This allows to simulate larger tubes than with molecular dynamics simulations being relevant for real devices. For all the applications one common versatile simulation platform has been developed.



David Kauzlaric studied Microsystems Engineering at the University of Freiburg and got his diploma in 2003. In the same year he started the work on his doctoral thesis at the Department of Microsystems Engineering in the Laboratory for Simulation of Prof. Jan G. Korvink.
