volScalarField Up
(
IOobject
(
"Up",
runTime.timeName(),
mesh,
IOobject::NO_READ,
IOobject::AUTO_WRITE
),
mag(U)*p
);

I am adding this line in createFields.H in myicoFoam solver which is nothing but the same solver icoFoam created in USER library. Then I am running the cavity case.

I am getting this file Up.C

at every time folder except 0/ as there is no <nonuniform> scalar written in it, I am unable to get it in paraview.

What is the possible solution to this problem?
