Hi all,

I try to use sampleDict to extract the velocity of several points on my computer but after I execute 'postProcess -func sampleDictU' there is no 'postProcessing' folder. However, on my cluster this command works well.

Is there anything that needed to be done before using the command 'postProcess -func sampledict*'?

By the way, is it the problem caused by different versions? The OpenFOAM I installed on my computer is OpenFOAM-7 and the one on my cluster is OpenFOAM4.0.



Best regards,
Stan

On your local machine no folder is created because it wasn't successful. The way you set up the sample dictionary will likely be different between openfoam versions. In any case here's an example I use for version 7 that works fine :

        libs ("libsampling.so");
        
        type                    sets;
        writeControl            outputTime;
        writeInterval           1;
        setFormat               raw;
        interpolationScheme     cellPoint;

        fields
        (
	    U
        );
        
        sets
        (
            line1
            {
                type            lineUniform;
                axis             y;
                start           (0 0 0);
                end             (0 1 0);
                nPoints        10;
            }
        );

Thanks for your suggestion. The example also works pretty well on my machine. And I just found that the 'sampling' folder is no longer located in the folder 'applications' and it is in the folder 'src'. I'll look into the differences of sample dictionaries. Thanks again!
