Hairpin vortices

In this tutorial, you will find an example of hairpin vortices behind a hemisphere. This case (which seems to be a simple one), can be rather tricky and requires some experience to trigger the hairpin vortices using coarse meshes. You will learn about

• understanding the physics
• case setup and workflow
• meshing
• running the simulation
  • steady-state
  • transient
• data evaluation
• mesh refinement

You can download the case files in this link.
