Dear All,

can anybody help me finding a list of cells, which have a boundary face?
any help would be appreciated

Go to all oundary patches and ask for faceCells(). This will give you a cell index for each face on the boundary. If a face has got 2 or more boundary faces, it will show up in faceCells() for more than one patch.

For examples, have a look at how RANS wall functions fix the value of epsilon in near-wall cells.

There is also a utility called 'cellSet' which takes a cellSetDict dictionary.

Use 'boundaryToCell' as the source (you'll understand if you read the dictionary)

The cellset can be displayed with foamToVTK .. -cellSet xxx

Dear All,

thanx for the fast answer!

Hi you all,

I'm Sergi and I'm quite new with all C thing and openfoam , I'm interested on that. I've just realized how to export the centers of the cells (hard work.. can't imagine..).

Now I'm interested on getting the list of the boundary cells, you say "Go to all boundary patches and ask for faceCells()" my question.. is.. well.. how?

Sorry for this kind of basic questions..

Hello Hrvoje,

Could you please tell me how to get the maximal value of the boundary cells of a certain Field A? Is it simply max(A.boundaryField()[patchID].patchInternalField())? Thank you in advance!

Bests,
