Hairpin vortices

In this tutorial, we will simulate hairpin vortices behind a hemisphere. This case (which seems to be a simple one), can be rather tricky and requires the use of some tricks 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
• Sampling and plotting
• Mesh refinement

You can download the case files in this link.
