Hi Foamers,

Are field operations on cell zones allowed in openFOAM?
I mean, if a have 2 volScalarField, namely A and B, and i create a third volScalarField C as:

volScalarField C = A + B

OF will automatically calculate C on every internal cell and every boundary face based on internal values and boundary values of fields A and B.

Now i want to perform the same calculation on cell zones. Something like

ForAll zones
C[zoneI] = A[zoneI] + B[zoneI]

Is there a way to do that without looping over all the cells of zoneI?

Thanks,
Andrea
