hi foamers,

I need some help with a OpenFOAM code manipulation.
First of all my case is naca profile in a o-topology.
For this case i analyze the force, lift and drag coefficient.

For the next step I need the help, my goal is to analyze a define
strip of my profile e.g. z-coordinate = 1 - 2 of the patch.

In the force.c I search the "wall" patches, like this loop
forAllConstIter(labelHashSet, patchSet_, iter){}
Bout in this loop a strip to define with coordinates,
but don't work? e.g. component(vector::Z)[facei].

Got anyone a idea , please post
Thanks
