Hi All,
In constructor of GeometricField class we have

GeometricField            (           const IOobject &            io,                              
          
          const Mesh &            mesh,                              
          
          const dimensioned< Type > &            dt,                              
          
          const word &            patchFieldType = PatchField<Type>::calculatedType()                              
          )

where default boundaryType is calculatedType.

How can I define GeometricField with zeroGradient patchFieldType??

Hi,

You can use just "zeroGradient" string or zeroGradientFvPatchField<Type>::typeName if you would like to be sure your modification survives rename of zeroGradient.

Hi Alexeym,
It tells me that zeroGradient was not declared in this scope...

Hi,

To use zeroGradientFvPatchField you have to include zeroGradientFvPatchFields.H. If you do not want to bother, use string "zeroGradient".

Hi Alexeym,
I added zeroGradientFvPatchFields.H but it still tells that zeroGradient was not declared in this scope.
My code is (in constructor)

A
(
    IOobject
    (
         "A",
         U.mesh().time().timeName(),
         IOobject::NO_READ,
         IOobject::NO_WRITE
    ),
    U.mesh(),
    dimensionedScalar("A", dimTemperature, 0.0),
    zeroGradient
),

Hi,

You could try to use more conventional C++ syntax (first one uses string, second uses static field):

A
(
    IOobject
    (
         "A",
         U.mesh().time().timeName(),
         IOobject::NO_READ,
         IOobject::NO_WRITE
    ),
    U.mesh(),
    dimensionedScalar("A", dimTemperature, 0.0),
    "zeroGradient"
),

or

A
(
    IOobject
    (
         "A",
         U.mesh().time().timeName(),
         IOobject::NO_READ,
         IOobject::NO_WRITE
    ),
    U.mesh(),
    dimensionedScalar("A", dimTemperature, 0.0),
    zeroGradientFvPatchScalarField::typeName
),

Now it works
Thank you so much Alexeym.
