Hi all,
I am new to OpenFOAM source code.
I wanted to know where in OpenFOAM code the variables are read.
e.g. if you open the createFields.H for icoFoam you will find

Info<< "Reading transportProperties\n" << endl;
IOdictionary transportProperties
(
IOobject
(
"transportProperties",
runTime.constant(),
mesh,
IOobject::MUST_READ_IF_MODIFIED,
IOobject::NO_WRITE
)
);

dimensionedScalar nu
(
transportProperties.lookup("nu")
);

Info<< "Reading field p\n" << endl;
volScalarField p
(
IOobject
(
"p",
runTime.timeName(),
mesh,
IOobject::MUST_READ,
IOobject::AUTO_WRITE
),
mesh
);


I hope these lines are reading the P, U and transportProperties directory.
I tried to debug in createFields.h file but I am not able to reach in source files
where the P,U and nu and their respective dimensions are read.
Can anybody tell me about the source files where OpenFoAM reads its variables.

with regards.
