Hello, I was trying to compile a solver which contains the function "gSum". There is an error saying there is no proper function for calling gSum.
Any suggestions?
Thanks

I suggest you include the relevant code you wrote and the exact error message.

gSum works only with basic arrays - Field<T>, List<T> and so on. gSum doesn't work with complex fields, like GeometricField, i.e. volVectorField, surfaceScalarField.

Sorry!

The line in the code that gives the error message:

sumV = gSum(alpha1*mesh.V());

(solver based on interFoam)

in createfields: const volVectorField& C = mesh.C();



The error message was given in german, that's why I tried to translate it as well as possible:

filename.H: in function "int main(int char**)":

filename.H: error: no proper function for calling gSum(Foam::tmp<Foam:: DimensionedField<double, Foam::volMesh> >)«

Problem solved! Had to use

sumC = gSum(C.internalField()*alpha1.internalField()*mesh .V());

instead of

sumC = gSum(C.internalField()*alpha1*mesh.V());
