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) ); |

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 Charlie |
