Micro Abstract:
Using boundary-conforming methods for co-rotating intermeshing domains is a complex task because the mesh has to be updated in every time step. Traditional methods like the elastic mesh update method require constant re-meshing due to mesh failure. We present a new, efficient approach, the Snapping Reference Mesh Update Method (SRMUM). It is based on a background mesh that constantly adapts to the current geometry. We apply the method to flow computations of plastic melt in twin-screw extruders.
