Hello everyone
How can I open a file only at first time step and write my data there? The problem is that, I need to restart the code, and when I restart the code, it opens a new file and write from "restartTime" there and I loose the transient data until "restartTime".
I want to use "if";

        label curTimeIndex = mesh.time().timeIndex();
        if(curTimeIndex == 1) {
	ofstream myfile1;
        myfile1.open ("kineticEnergyFFD.txt");
        }

but it give me this error(without if everything is correct, but I have a problem in restarting the code as I explained earlier);

postprocessingFFD.H:731:3: error: ‘myfile1’ was not declared in this scope
   myfile1 << runTime.timeName() << "          " << avekineticEnergy0 << "          " << minkineticEnergyNew << "          " << maxkineticEnergyNew <<

Thanks,
Farzad
