Dear all,

This may be another stupid question, but I am so confued. So sorry to bother you.

When we construct mesh object for manipulation such as

Info<< mesh.cellVolumes() << endl;

We construct the mesh object by

Foam::polyMesh mesh
{
    IOobject
    (
        defaultRegion,
        runTime.timeName(),
        runTime,
        IOobject::MUST_READ
    )
};

So, why construct mesh based on path [runTime.timeName()] instead of maybe path [runTime.constant().polyMesh()] (or something representing case/constant/polyMesh/)?

I am confused that the mesh is supposed to relate to [constant/polyMesh/] directly rather than [time] directory, right?

If not, how does the [mesh] object get information (such as points, faces) from [constant/polyMesh] directory?

Thank you very much if any kind foamer could help me.

Best regards,
Ary
