Effizienter fluidischer Transport mittels mikromechanischer Aktoren: Numerische Herausforderungen beim Entwurf

Studying the interaction between moving bodies and surrrounding fluids is of interest, for example, if viscous damping effects and their influence on the dynamic response of a system have to be determined or if fluid-structure interaction is a part of the system's operating principle. A crucial point in this respect is the moving mesh in the fluidic domain caused by the motion of the body, which requires specific meshing algorithms and mesh motion strategies. In cases of simple implementations complex motion patterns of the structure are likely to lead to convergency problems. In order to prevent them extensive manual mesh adaptations are required. If instead more advanced methods are available, the algorithms may be capable of automatically adapting the mesh to the moving body in an adequate manner.
