Supersonic Wing Flutter

Luca

Hi everybody! I want to simulate a wing in supersonic fligth. I made my mesh, run a steady solution, I have a curve shock behind the wing. I want to describe accurately the shock because it influences aerodynamic forces on wing. Anybody can suggest me how to make my analysis more accurate? Do I have to make a finer grid in the shock-position (or adapt the grid there, another possbile solution...). What kind of model should I use? Thank you for any suggestion. Luca
