Hairpin vortices

In this [http: //www.wolfdynamics.com/wiki/hairping_vortices.pdf tutorial] you will find an example on vortices behind a hemisphere. This is the simplest possible example of an external flow. As you will see even this case can be rather tricky and you will need all your experience and knoledge to tackle the simulation. You will learn about

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

You only have to download it once, you can find all the cases in the tarball, which you need for all the tutorials of Joel Guerrero.
