Hi everybody,

I want to have the positions of cell centers (x,y,z) as out put in my time directories. I know that the utility "writeCellCenters" do what I want, but I prefer to get them automatically.

I searched and found out that functionObjects are capable of doing so. I found from

http://openfoamwiki.net/index.php/Co...unctionObjects

that the type writeAdditionalFields is exactly what I want. I found this example in their documentations:

functions 
(
    writeEnthalpy 
    {
        functionObjectLibs   ("libsimpleFunctionObjects.so");
        type                 writeAdditionalFields;
        fieldNames           ( h mu );
        after 0.1;
    }
);

But now I do not know how to use it to get x, y and z positions of cell centers of my mesh.

Any help is appreciated.
