I did a bit of digital time travelling into OpenFOAM's past and here's what I could find out: 1- The User Guide for OpenFOAM 1.6.* was the last one that had a reference to this feature in one of the tables, as shown in image "Excerpt from User Guide 1.6.png". For comparison, the respective table in the User Guide for OpenFOAM 1.7.* is shown in image "Excerpt from User Guide 1.7.png". 2- As ThomasM87 points out, there is still a remnant in the User Guide to this date, referring to this feature. It's shown in the image "Excerpt that is still present to this day.png". I'm still looking through the evolutions of OpenFOAM's source code, to see if I can figure out how it was once implemented and to see if there is a possibility to either implement this code again or not. ---------------- But my guess is that this kind of sampling has been shifted to relying on the "foamCalc" utility or the function object "calcMag" to generate the necessary intermediate fields for sampling. This way it makes things more generic and this way it's not necessary to meld code into the sampling infrastructure. In this light, it seems that this results in two tasks: a) Feature request to have "foamCalc" available as a function object as well... namely, to further extend the function object library "src/postProcessing/functionObjects/fvTools" to use all of the available features at "src/postProcessing/foamCalcFunctions". b) Updating the documentation to rephrase the text represented in the image "Excerpt that is still present to this day.png". |

Additional historic note: the utility "sample" was pretty much rewritten for OpenFOAM 1.5. This was when this feature of processing components and magnitudes was dropped from being done directly in "sample". In theory, it seems possible to re-implement this by using a few little pieces of code as reference from the old code from OpenFOAM 1.4.1 and using them in "src/sampling/sampledSet/sampledSets" and "src/sampling/sampledSurface/sampledSurfaces". But from I know about OpenFOAM's source code evolution, this would not be the intended evolutionary direction, but instead be in favour of "a)" on my previous comment. |
