it seems to work but I'm not 100% sure about the results...

Code:
functions
{
    cuttingplane_average
    {
        type            faceSource;

If I understand you correctly, you want to do a plain average of the fields over the existing time snapshots?

In addition, do you mean that the average results for a dynamic mesh are acceptable for doing

To be more precise, i'm using the solver icoDyMFoam of OpenFOAM 1.4.1. The mesh is solved with the following options :

Basically, I am looking to do something like:
