Hi all.
I have just used openfoam. I has LES model and it runs good. And now, I would like to calculate some terms in LES as first term1 = nu{p*[d2(ui/xi)]} and second term2 = p*[d((ui uj)/xj)]. After that, get average term1 - average term2. d2 is second derivative and d is first derivative. HTML Code:
volScalarField term1
(
IOobject
(
"term1",
runTime.timeName(),
mesh,
IOobject::NO_READ,
IOobject::AUTO_WRITE
),
p*fvc::laplacian(U)
);
volVectorField term2
(
IOobject
(
"term2",
runTime.timeName(),
mesh,
IOobject::NO_READ,
IOobject::AUTO_WRITE
),
p*fvc::grad(phi,U)
);
HTML Code:
/opt/openfoam211/src/OpenFOAM/lnInclude/GeometricField.C:209:1: note: Foam::GeometricField<Type, PatchField, GeoMesh>::GeometricField(const Foam::IOobject&, const Mesh&, const Foam::dimensionSet&, const Foam::word&) [with Type = double, PatchField = Foam::fvPatchField, GeoMesh = Foam::volMesh, Foam::GeometricField<Type, PatchField, GeoMesh>::Mesh = Foam::fvMesh] /opt/openfoam211/src/OpenFOAM/lnInclude/GeometricField.C:209:1: note: candidate expects 4 arguments, 2 provided /opt/openfoam211/src/finiteVolume/lnInclude/readPISOControls.H:3:15: warning: unused variable ‘nOuterCorr’ [-Wunused-variable] /opt/openfoam211/src/finiteVolume/lnInclude/readPISOControls.H:15:16: warning: unused variable ‘transonic’ [-Wunused-variable] make: *** [Make/linux64GccDPOpt/mypisoFoam.o] Error 1 Thanks.

For term 1, you write ui/xi. This would be the divergence of u, not the laplacian. The laplacian of a vector is a vector, while you store it as a scalar. Is this line 209, that gives you the error message?

Sorry, i think I had mistake description filed. The term1 is really second derivative of velocity Ui as [d(ui^2)/d(xj^2)] and other term2 is first derivative of uiuj as [d(uiuj)/dxj)].
I fixed code the term1 is ok but term2 I think It is still error. HTML Code:
Info<< "Reading/calculating laplacian of velocity \n" << endl;
volVectorField plapU
(
IOobject
(
"plapU",
runTime.timeName(),
mesh,
IOobject::NO_READ,
IOobject::AUTO_WRITE
),
p*fvc::laplacian(U)
);
Info<< "Reading/calculating divergence of velocity \n" << endl;
volVectorField pdivU
(
IOobject
(
"pdivU",
runTime.timeName(),
mesh,
IOobject::NO_READ,
IOobject::AUTO_WRITE
),
p*fvc::div(U,U)
);

Which line is giving you the error message? I'd rather not guess.

Sorry Bernhard, this is error in terminal. I don't know the line caution error. I only see 68:21 caution error.

Hi Foamer
I need DU/Dt values for all grids. How can i calculate and write this parameter. Any suggestion will be appreciated. Best regards. Thanh |

Thank your reply.
I sorry about my presentation and English. My English only immediate. Really I would like to find derivative of velocity mention above. The first example I setup derivative is error. So the second example I changed otherwise but it still error. My example is pitzdaily use LES dynOneEqEddy and pisoFoam solver. Code:
Info<< "Reading/calculating laplacian of velocity \n" << endl;
volVectorField plapU
(
IOobject
(
"plapU",
runTime.timeName(),
mesh,
IOobject::NO_READ,
IOobject::AUTO_WRITE
),
p*(fvc::laplacian(U))
);
/*Info<< "Reading/calculating divergence of velocity \n" << endl;
volVectorField pdivU
(
IOobject
(
"pdivU",
runTime.timeName(),
mesh,
IOobject::NO_READ,
IOobject::AUTO_WRITE
),
p*(U&fvc::grad(U))
);*/
Info<< "Reading/calculating divergence of velocity \n" << endl;
volVectorField pdivU
(
IOobject
(
"pdivU",
runTime.timeName(),
mesh,
IOobject::NO_READ,
IOobject::AUTO_WRITE
),
p*fvc::div(U*U)
);
