read volField from startTime or timeName directory
 
Hi all,

I would like to in a post-processing tool read/construct a volScalarField using IOobject from whether the startTime directory or current time directory, depends on where the corresponding IO file exists. Could someone suggest an elegant way to do this?

Like:

Code:
autoPtr<volScalarField> pPtr
(
    IOobject
    (
        "p",
        runTime.timeName(),
        mesh,
        IOobject::MUST_READ,
        IOobject::NO_WRITE
    ),
    mesh
);

if (pPtr.invalid())  // p-file may not exist in current time directory
{
pPtr.reset
(
    IOobject
    (
        "p",
        runTime.startTime(),
        mesh,
        IOobject::MUST_READ,
        IOobject::NO_WRITE
    ),
    mesh
);
}
;

Not sure if it works. Any hints?
