Description

This LS-DYNA simulation shows a simple ICFD problem with adaptivity. A new fluid volume mesh is generated every few fluid timesteps focusing on the regions where vortexes occur by adding more elements while using a coarser mesh in regions where the flow is smooth. This powerful tool must however be handled with care. Remeshing is a costly process which can not be scaled on multiple CPUs. Furthermore, every time a remesh occurs, the topology of the mesh is changed which can yield inaccuracies.
