Our research group studies systems in which physical and mechanical processes with distinct characteristic scales (large versus small, slow versus fast, localized versus collective) are equally important – and interacting. To overcome this multi-scale challenge, the group develops and applies high-performance computing, advanced algorithms, statistical, continuum and micro-macro theories, as well as experiments. Most applications involve combining numerical methods and theories from fluid and solid mechanics. Examples include particles suspended in (non-) Newtonian fluids, molecular flow through nano-porous media, micro-structured modern materials, and granular systems displaying both solid-like and fluid-like behaviour depending on the prevailing conditions. Industrially relevant multi-scale systems are too big to be simulated with a single monolithic method, and hence it is essential that multi-scale methods are being developed by a research group that brings together a combination of disciplines and expertises.
