me again... fyi: basically I just commented out the not needed points and faces... this worked quite good.
Now, I would like actually write out the complete mesh information including a boundary, neighbour, owner files.
Do you have a hint, how I can do this?

Sampling data from the cells close to a boundary or a wall might not be a trivial matter. That is why I am calling back this some two years old thread, which is closely related to my present question.
My geometry is composed of some curved walls and I need to collect some data, like U and p, from the very first layer of cells near the wall. It seems pretty straightforward to do that with the "sample" utility, if I new the coordinates of each cell centre, by just listing them under the type "cloud" in the sampleDict file. But this is where things go awry.
So, is there an easy way to get the coordinates of some specific cells, in particular those bordering a wall? I would guess that cellSet might be an answer, but I could not find something like a source "boundaryToCell" in the topoSetDict.
Or, alternatively, can anyone devise another approach to pick these close-to-the-wall cells values of velocity and pressure? BTW, this is almost exactly the question posed by Alejandro, above, but his problem was solved in a different way, so the the question remains alive. I would appreciate any suggestion on that.
I am using OpenFOAM 2.0.0.
