Abstract: Traditionally numerical modelling on scales larger than individual atoms has been done as continuum modelling based on solving a set of differential equations. In order to solve diff. equations numerically they have to be made discrete. Particle based methods skip the redundant step of constructing a differential model of an originally discrete system and there after solving the discrete version of the diff. equations. The particle based method strive to find a relevant length scale on which a system is naturally discrete and then simulating the dynamics via equations of motion. Such a length scale may be e.g. grain-boundaries, fibers, cells, etc. The talk is focused on applications and example like e.g. glacier calving, fragmentation and cytoskeleton dynamics."
