Hi!

I defined a symmetric tensor field symGradU from a field U
Code:
volSymmTensorField symGradU = twoSymm(fvc::grad(U));
When I plot the field name using
Code:
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
Code:
 symGradU.name() = "symGradU" ;
but it doesn't work.

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

Regards,
Cyp

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

Code:
        //- 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:

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