Hi Foamers,
I want to access boundary face temperatures in chtMultiRegionFoam (I am using OpenFoam1612+).
I can reach temperature values when running in serial.

// For the boundary region 6

forAll(thermoFluid[i].T().boundaryField()[6], faceI)
{
internaltemp[faceI]=thermoFluid[i].T().boundaryField()[6][faceI];
}

But in parallel run, I can only take procesor0 values.
How can i access other processor's temperature values?

Thanks for any help

I found that it already runs on parallel processors but i could not visualize the following line for all processors:

Info<<"totalNCoarseFaces: "<<totalNCoarseFaces_<<" Local:"<<nLocalCoarseFaces_<<" Pmaster: "<<Pstream::myProcNo() <<endl;

Info, cout, fprintf are only working on master node. Hence, they were not the commands i require for this case. To be able to print variables on the terminal screen Pout or Sout should be use.
Following code prints on terminal for each processors:

Sout<<"totalNCoarseFaces: "<<totalNCoarseFaces_<<" Local:"<<nLocalCoarseFaces_<<" Pmaster: "<<Pstream::myProcNo() <<endl;

Temperature access on each processor is handling with this code. All the processors reads their own mesh and faces of boundaryfield 6. Nothing is changed apart from internaltemp[treshold+faceI] for other processors:

if(Pstream::myProcNo()==0){
internaltemp[faceI]=thermoFluid[i].T().boundaryField()[6][faceI];
if(faceI==4928){
Pout <<" Sout myProcNo():"<< Pstream::myProcNo()<<" i:"<< faceI << ":T:"<<internaltemp[faceI] ;
}
}
if(Pstream::myProcNo()==1){
internaltemp[4929+faceI]=thermoFluid[i].T().boundaryField()[6][faceI];
Pout <<" Pout myProcNo():"<< Pstream::myProcNo()<<" i:"<< faceI << ":T:"<<internaltemp[4929+faceI] ;
}
}
