![]() Configuration File OptionsĪside from the mesh, the only other file required to run the SU2_CFD solver details the configuration options. The figure below gives a view of the mesh.įigure (1): Far-field and zoom view of the computational mesh. The airfoil surface uses a flow-tangency Euler wall boundary condition, while the farfield uses a standard characteristic-based boundary condition. It consists of 10,216 triangular cells, 5,233 points, and two boundaries (or “markers”) named airfoil and farfield. The unstructured mesh provided is in the native. The aim is to find the flow solution and the adjoint solution with respect to an objective function defined as the drag on the airfoil. This problem will solve the Euler equations on the NACA0012 airfoil at an angle of attack of 1.25 degrees, using air with the following freestream conditions: ![]() More information on these airfoil sections can be found here or in the book ‘Theory of Wing Sections’ by Abbott and von Doenhoff. The numbering system is such that the first number indicates the maximum camber (in percent of chord), the second shows the location of the maximum camber (in tens of percent of chord) and the last two digits indicate the maximum thickness (in percent of chord). The NACA0012 airfoil is one of the four-digit wing sections developed by the National Advisory Committee for Aeronautics (NACA), and it is a widely used geometry for many CFD test cases. If you have yet to complete this requirement, please see the Download and Installation pages. Again, we assume that you have already obtained and compiled the SU2_CFD code (either individually, or as part of the complete SU2 package) for a serial computation. The following tutorial will walk you through the steps required to compute the flow and adjoint solutions around the NACA 0012 airfoil using SU2. The files are in QuickStart/ and can also be found in the TestCases repository under TestCases/euler/naca0012. Two files are needed as input to the code: a configuration file describing the options for the particular problem, and the corresponding computational mesh file. For the other tutorials, the files will be found in the TestCases/ repository. The files necessary to run this tutorial are included in the SU2/QuickStart/ directory.
