Missing stressComponents Function
 

Greetings!

I use the 5.x version of OpenFOAM and I have a laminar flow simulation using simpleFoam from which I'd like to get the stress field. In previous versions, I was able to use the "stressComponents" function, which provided good results. However, in this version, it has been superseded by the -postProcess solver option, with the suggested use "simpleFoam -postProcess -funcs '(R components(turbulenceProperties:R))'". When using this I get a stressField that is essentially zero (values are very small, in the order of E-38). I'm a new foamer, but I believe this is due to the "R" being related to turbulence which is not my case. Is there any other way to get the stress field for this simulation?
