Hi Julien,

Well, my hunch I told you about in todays email about changeDictionary was right. Based on the tutorial "incompressible/pisoFoam/les/pitzDailyDirectMapped", here is a modified file changeDictionaryDict in the folder system:

/*--------------------------------*- C++ -*----------------------------------*\
| =========                 |                                                 |
| \\      /  F ield         | OpenFOAM: The Open Source CFD Toolbox           |
|  \\    /   O peration     | Version:  1.7.1                                 |
|   \\  /    A nd           | Web:      www.OpenFOAM.com                      |
|    \\/     M anipulation  |                                                 |
\*---------------------------------------------------------------------------*/
FoamFile
{
    version     2.0;
    format      ascii;
    class       dictionary;
    location    "system";
    object      changeDictionaryDict;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

dictionaryReplacement
{
    boundary
    {
        frontAndBack
        {
            type            wall;
        }
    }
}


// ************************************************************************* //

Then simply run changeDictionary on the case folder and voilá, boundary changed
If you search for other changeDictionaryDict files, you'll find more examples.

And here is the online Doxygen help for changeDictionary.C.
