Hi Everyone,

I am trying to output every timestep data of volVectorField like U,T,p into arraies constructed by myself with RTS mechanism , would that be possible and anyone can give me some advices, I am writting my .C and .H files, just stunned by this problem. Thank you!

My member function looks as follows:

[
namespace Foam
{
defineTypeNameAndDebug(OutputU, 0);
defineRunTimeSelectionTable(OutputU,word);
addToRunTimeSelectionTable
(
OutputU,
OutputU,
word
);
}

// * * * * * * * * * * * * * * Member Functions * * * * * * * * * * * * * * //

void Foam::OutputU::volecityoutput() const
{
volVectorField& U=U.();
forAll(U,celli)
{
std::cout<<U[celli]<<"\n"<<std::endl;
}
}
]

Terminal tells me that U is not declared, I don't know how to declare it, I think with createFields.H I can directly use variable U.
