Airfoil simulation
Hi folks!!

I have to simulate a 2D airfoil. I generated the mesh and now I want to simulate it in CFX. Does anybody know a workshop or stuff like that which guides me trough the simulation. I donīt have any experience and so I would be glad if one could help me.

Thanks a lot in advance!!

Re: Airfoil simulation
there is a a tutorial case for supersonic flow on airfoil. you will get help from it.

good luck
