I ran a turbulent channel flow calculation and now I want to sample the obtained Reynolds Stress Tensor R with the post processing sample tool. However the tool does not work if I put a capital R (for Reynolds Stresses) in the fields part of the sampledict file:

Code:
fields
(
     U
     R
);
Has anyone succeded in doing this? What do I have to do to apply the samples tool on R? Thanks a lot

Try to sample UPrime2Mean instead of R.

I had problems with sampling UPrime2Mean too and I was suggested to firstly get UPrime2Mean components (foamCalc components UPrime2Mean) and then apply sample to each component separately.

The UprimeToMean field is a symmetric tensor field and this fieldtype is really tricky. The foamToTecplot converter ignores it too. But with the foamCalc you can split the symmetric tensor field into its componets UprimeToMeanxx, UprimeToMeanyy, UprimeToMeanzz ... This should work :-D
