Hello,

As stated in the title, the function postProcess -func sampleDict is not returning any data. This has only happened once I repurposed my sampleDict to sample values on an arbitrary plane; when I ran the same function for a sampleDict sampling along an arbitrary line, a postProcessing directory was returned containing all the data. My sampleDict file is below:

FoamFile
{
    version     2.0;
    format      ascii;
    class       dictionary;
    object      sampleDict;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //
surfaceFormat raw;
interpolationScheme cell;
sets();
surfaces
(
    constantPlane
    {
        type              plane;    // always triangulated
        basePoint       (0.05 0.05 0.3);
        normalVector  (0 0 1);
    }
);
fields
(
    Uz
);

Thank you in advance for any help.

I found the solution to my own problem:

Sampling is not a function that has been 'superceded' (OF error's words) by calling sampleDict using postProcess, which was why I used the command

postProcess -func sampleDict

because of this, I had to include in my sampleDict the following (per OF error's instructions):

type    sets;
libs    ("libsampling.so");

*I did have this in my original sampleDict (just got lost amongst comments when I was copying pasting onto my post), which was why the command I used worked when I sampled along a line*

SOLUTION:

change

type    sets;

to

type    surfaces;

and voila! It works! Hope this helps someone!

Hello.

I have a similar problem running "postProcess -func sampleDict". No folder named "postProcessing" is created.

It seems like it is reading the my velocity field "U.air".
See my sampleDict below. Any help, is much appreciated.

Hello Scrubber,

Does OF give you any errors when you try and run sampleDict?

[scrubber]

Hello Tmr2044.

If I try to just run the command simpleDict, OF give this error
jens@jens-VirtualBox:~/OpenFOAM/jens-6/run/test_case/BFS/DPMFoam_2WC$ simpleDict
simpleDict: command not found

I get no error from OF when running "postProcess -func sampleDict", but no postProcessing folder is created.
