Hi Foamers,

I've got confused by the output of the utility "Lambda2" in openFOAM,

When I typed the command Lambda2 in OpenFOAM, the output information is like the following:

reading U 20
writing -Lambda2

My question is the values written is Lambda2 or - lambda2? Thanks very much!!

Charlie

Let's have a look in applications/utilities/postProcessing/velocityField/Lambda2/Lambda2.C:
Code:
        volScalarField Lambda2
        (
            IOobject
            (
                "Lambda2",
                runTime.timeName(),
                mesh,
                IOobject::NO_READ,
                IOobject::NO_WRITE
            ),
            -eigenValues(SSplusWW)().component(vector::Y)
        );
To me it appears as if it writes -lambda2.

Hi Haakon,

Thanks a lot, I think you are right, if we compare the Q with Lambda2, we could also confirm that the command Lambda2 is writing -Lambda2, Thanks!

Best
