Can't output Reynolds stress in pisoFoam

I am trying to run a channel flow using the k-epsilon model, with the pisoFoam solver. While the result seems to be converging, and I can see outputs for U, k, epsilon, nut, p, phi, I don't see any output files for R (Reynolds stress). Is there any way I can make the solver output R as well ? I can of course calculate R from k, nut and grad U, but it would be more convenient to just get R outputted directly.
I am attaching the contents of the 0/R file below. Any help will be appreciated. regards Amitabh /*--------------------------------*- C++ -*----------------------------------*\ | ========= | | | \\ / F ield | OpenFOAM: The Open Source CFD Toolbox | | \\ / O peration | Version: 2.1.1 | | \\ / A nd | Web: www.OpenFOAM.org | | \\/ M anipulation | | \*---------------------------------------------------------------------------*/ FoamFile { version 2.0; format ascii; class volSymmTensorField; object R; } // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // dimensions [0 2 -2 0 0 0 0]; internalField uniform (0 0 0 0 0 0); boundaryField { inlet { type zeroGradient; } outlet { type zeroGradient; } fixedWalls { type kqRWallFunction; value uniform ( 0 0 0 0 0 0 ); } frontAndBack { type empty; } } // ************************************************** *********************** // |

You could use the R utility that is already there in OpenFOAM. Just go to your case directory and type
Code:
