I just wonder is it possible to model fluid-structure interaction with SimScale ? I thinking about case where there would be a moving solid item in a air channel/duct. Particularily I would be interested about an oscillating cantilever structure which itself generates an airflow. So in that case the move would be oscillating with some period. What are the means to describe a move of a surface in SimScale ? Or just think first a bit simpler case, a solid ball dropped in a fluid. How can I model it’s move in order to simulate the flows it generates ? In large move the mesh should be refined. How this can be done in SimScale ? Would the software be able to do remeshing automatically ?
