CFD Online Discussion Forums - [volFieldValue] the CellZone fields are not visible in Paraview

Hi there,

I am using the 'volFieldValue' function to write fields (U p) of a specific 'cellZone' called 'Box1' during runtime, without writing the fields all over my domain. This writes the fields to my time folders, under names like "U_cellZone-Box1" and "p_cellZone-Box1". So far, so good.

However, I cannot visualise these fields in Paraview. I have enabled the "Read zones" and "Copy data to cell zones" options. I can see my cell zone using the Extract Block filter, but I cannot see the fields. I've also tried changing the filenames from "U_cellZone-Box1" to "U" for example, but this hasn't helped. I also run 'foamToVTK -cellZone-Box1 -parallel'. It writes the mesh of the cellZone in VTK format, but not the fields, so the same problem.

Do you have any idea how I should manipulate these cellZone fields to visualise them in Paraview?

Best regards,

Ege

This is the function I am using inside my ControlDict:

Code:

    volFieldValue1

    {

        type                volFieldValue;

        libs                 ("libfieldFunctionObjects.so");

        log                  true;

        writeControl    runTime;

        writeInterval   0.005;

        writeFields     true;

        regionType       cellZone;

        name               Box1;

        operation         none;

        fields

        (

            U

            p

        );

    }
