David Schneider (Technical University of Munich): deal.II and high-order coupling with preCICE


Comment on slides 9 and 10: the missing vertices in the preCICE exported meshes have not been filtered out by preCICE, but by paraViews default visualization settings. Increasing the maxium number of glyph samples for the respective coupling meshes results in a 'complete' coupling mesh without missing nodes. Still, depending on the selected mapping method and the participant you use to export the coupling mesh, preCICE might filter out coupling nodes. 

A broad overview of the deal.II-related work around preCICE.
