Hi!

I defined a symmetric tensor field symGradU from a field U

volSymmTensorField symGradU = twoSymm(fvc::grad(U));

When I plot the field name using

Info << "Field symGradU name = " << symGradU.name() << endl;

I get
Field symGradU name = twoSymm(grad(U))

I want to change this name ("symGradU"), in particular to write the output correctly. I tried

 symGradU.name() = "symGradU" ;

but it doesn't work.

Do you know a simple manner to rename a field ??

Regards,

You can do it during construction, (though it must be possible to do it afterwards too...). From GeometricField.H:

        //- Construct as copy resetting IO parameters
        GeometricField
        (
            const IOobject&,
            const GeometricField<Type, PatchField, GeoMesh>&
        );

        //- Construct as copy resetting name
        GeometricField
        (
            const word& newName,
            const GeometricField<Type, PatchField, GeoMesh>&
        );

So you could use:

    volSymmTensorField symGradU
    (
        "symmGradU",
        twoSymm(fvc::grad(U))
    );

Thank you very much ! It is exactly what I was looking for !
