Dear Foamer,

Is there a function/method to check if a file is a well formatted foamFile? Namely, if it start by a valid header? I'm looking for something, which return a bool, then I can handle the different cases...

For example:

example 1: well formatted

FoamFile
{
    version     2.0;
    format      ascii;
    class       vectorField;
    object      values;
}

example 2: well formatted

// blah blah blah
FoamFile
{
    version     2.0;
    format      ascii;
    class       vectorField;
    object      values;
}

example 3: badly formatted:

//blah blah blah
324
456.8
5.7
34

Greetings Marcel,

In OpenFOAM's source code applications folder, you should be able to find several examples like the following, which can be seen online here:

https://github.com/OpenFOAM/OpenFOAM...ryLayer.C#L167

        // Turbulence omega
        IOobject omegaHeader
        (
            "omega",
            runTime.timeName(),
            mesh,
            IOobject::MUST_READ,
            IOobject::NO_WRITE,
            false
        );

        if (omegaHeader.headerOk())
        {
            volScalarField omega(omegaHeader, mesh);
            omega =
                epsilon
               /(
                   Cmu*k+dimensionedScalar("VSMALL", k.dimensions(), VSMALL)
                );
            omega.correctBoundaryConditions();

            Info<< "Writing omega\n" << endl;
            omega.write();
        }

As you can see, it first only loads up the header mechanism, to check if the header is OK. Only then does it finally load the whole field file and process it.

Best regards,
Bruno
