Hi,

I have multi-regions in my problem. I want to define different transport properties which are constants for each region feild. This is the way I am doing,

in the file createFluidFeilds.H

PtrList<dimensionedScalar> rhoFluid(fluidRegions.size());

Info<< " Adding transport properties to fluid field\n" << endl;
forAll(fluidRegions, i)
{
IOdictionary fluidtransportProperties
(

IOobject
(
"transportProperties",
runTime.constant(),
fluidRegions[i],
IOobject::MUST_READ,
IOobject::NO_WRITE
)
);

Info<< "\tReading fluid density\n" << endl;
rhoFluid.set
(
i,
new dimensionedScalar
(
fluidRegions[i].fluidtransportProperties.lookup("rho")
)
);
}


I want to have different "tranportProperties" dictionary files for each region.Is this method is correct?.

or,

PtrList<dimensionedScalar> rhoFluid(fluidRegions.size());

Info<< " Adding transport properties to fluid field\n" << endl;
forAll(fluidRegions, i)
{
fluidtransportProperties.set
(
i,
new IOdictionary fluidtransportProperties
(

IOobject
(
"transportProperties",
runTime.constant(),
fluidRegions[i],
IOobject::MUST_READ,
IOobject::NO_WRITE
)
)
);

Info<< "\tReading fluid density\n" << endl;
rhoFluid.set
(
i,
new dimensionedScalar
(
fluidRegions[i].fluidtransportProperties.lookup("rho")
)
);
}


Please anyone help me.

I all,


I had the same problem and I fixed it with a simple method.



PtrList<dimensionedScalar> rhoList(solidRegions.size());


forAll(solidRegions, i)
{
IOdictionary properties
(
IOobject
(
"properties",
runTime.constant(),
solidRegions[i],
IOobject::MUST_READ_IF_MODIFIED,
IOobject::NO_WRITE
)
);


rhoList.set
(
i,
new dimensionedScalar
(
properties.lookup("rho")
)
);
}


Like this, for every region it read a properties file in the constant/region folder. And then it fill the rhoList with the corresponding value in the corresponding properties file for the corresponding region. In my case it's solid but I guess it's exactly the same for you


I hope it helped you

Sorry for bad english
