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
