how to rename a field defined from others fields ?

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))

    );
