Hi guys, i have done a simple mesh of an airfoil, i would like to know how to extract the coordinates of points of the mesh that are on the airfoil patch

Thanks you for any answers

Hi!

You need it for external processing? This is a pretty brute force solution, but in the polyMesh/boundary file you can find the starting face of that patch and the number of faces. then in the polyMesh/faces file you can find the points for these faces. In the polyMesh/points file you find the coordinates for these points.

But there is a much simpler way using paraView. Open the case, load only the needed patch, create a SpreadSheet view, and you will find the coordinates in the Points column. And you can export it as a csv file. This is simpler, but the first method is more challenging
