OpenFoam ploting Field
 

Dear Foamer,
I would like to create a field Ser, with
Ser=fvm::ddt(T)+(U & fvc::grad(T))
and using paraview to show Ser on each cell of my domain. I put this way but still have pb in compiling:

volScalarField Ser
(
IOobject
(
"Ser",
runTime.timeName(),
mesh,
IOobject::NO_READ,
IOobject::AUTO_WRITE
),
fvm::ddt(T)+(U & fvc::grad(T))

);

//Ser.write()
How can I proceed ?
your insight will be appreciated.

What is the problem? What is mentioned during the compilation process?

Thanks you romant. I finally solved the issue using fvc instead of fvm on Ser expression.
