Using probe function or sample utility on a patch
 
I am doing a comparison between wind tunnel results and OpenFOAM simulation. Available from wind tunnel are the pressure coefficients (Cp) on 32 points (using pressure measuring instruments attached to the body). The coordinates of those points are available. I need to get P & k fields on the body patch at those 32 points using OpenFOAM.

in probe function & sample utility do not ask for the patch at which I want my results.

I mean, the coordinates of a point may not guarantee that It belongs to the patch (due to lack of accuracy of snappyHexMesh). How can get my results at the patch using points' coordinates (to find the closest point at the patch to the point with given coordinates)?

Is there any other function/tool to do the job?

Thanks!
