Hi all
I want to know about IOobject and objectRegistry. I have searched a lot about it but I didn't find out it completely!
just I know that IOobject is a class for input/output variables!
e.g. that is used for Reading T in createFields.H .
what is IOdictionary ?
what mesh is used in arguments ?


IOdictionary transportProperties
(
IOobject
(
"transportProperties",
runTime.constant(),
mesh,
IOobject::MUST_READ,
IOobject::NO_WRITE
)
);

I will be thankfull if explain for me about it.

IOdictionary transportProperties // indicates that you read from the dictionary file transport Properties
(
IOobject // inside transport properties you want a specific object or in this case file
(
"transportProperties", // Name of the dictionary file
runTime.constant(), // where the file is stored. runTime for which time and constant the constant folder
mesh, // is the object registry. It is a way of understanding the data inside OpenFOAM for its communications. Bascially this value will be used on the entire mesh
IOobject::MUST_READ, // self explanatory
IOobject::NO_WRITE // self explanatory
)
);

I will be thankfull if explain for me about it.
