Generally, OpenFOAM uses the following codes to read the initial pressure field as follows:

volScalarField p
(
IOobject
(
"p",
runTime.timeName(),
mesh,
IOobject::MUST_READ,
IOobject::AUTO_WRITE
),
mesh
);

The program will look for p from case/0/p, but now if I need to find p from case/Re/0/p, how should I write the codes?

Thanks a lot!
