Running k-epsilon with simpleFoam I am using "sample" to sample values at certain locations. This works fine for values like U and k, that are generated during run time. However, it does not work for values like, turbulenceProperties:R and wallShearStress, which is generated by the postprocessing functionality.

For the turbulent stress tensor I get the error message

Code:
--> FOAM Warning : 
    From function Foam::label Foam::sampledSets::classifyFields()
    in file sampledSet/sampledSets/sampledSetsGrouping.C at line 140
    Cannot find registered field matching turbulenceProperties:R

My sample-file looks like this

// ************************************************************************* //
turbulenceProperties:R is generated by

The sample file is run by

Code:
simpleFoam -postProcess -func sample -latestTime
"turbulenceProperties:R" exists lik a file just like U and k, so I do not understand why there is a problem sampling it. Does anybody have an idea about how to solve this?

I think I solved it, with help from this thread.

One additional thing I needed to do was to remove "simpleFoam" also from the command calling on sample.

It works for turbulenceFields:R also, not only for the components as in the mentioned link.
