Dear all,

I am using OpenFOAM to calculate the flow around airfoils I would like to create a polyline a certain distance from the airfoil (equidistant!) and the extract data from this polyline in order to create a chart. Does anybody know how to do it?

Thank you for your attention.

Hi Josť,

here is an idea:
Create a postprocessing utility which uses OpenFOAMs wallDist function:

#include "wallDist.H" // include before main()

. . .

wallDist y(mesh, true); // calculation of wall distance
y.write(); // write into time step directory

. . .

In ParaView you can use the "Filters->Alphabetical->Contour" filter to extract the iso surface based on wall distance. From this surface you can cut iso lines and make your further postprocessing on it.
