Aerodynamics

This tutorial walks you through how to set up and run an Aerodynamics simulation of a NACA0012 airfoil on the Rescale platform. This example uses the incompresible solver in SU2 and solves for 5 degree angle of attack. For a DOE simulation of NACA0012 airfoil for multiple angle of attack refer to the SU2 DOE Tutorial. Paraview is used for post-processing results from SU2.
