Hi,
i have a multi region simulation and working on some postprocess routines. However I have to specify each time the region to get the value. However, I would like to have the functions looping over all regions.

functions
{

        CellVolumeSteel
        {       
                // Mandatory entries (unmodifiable)
                type            writeCellVolumes;
                libs            (fieldFunctionObjects);
                
                // Optional (inherited) entries
                region          steel;
                enabled         true;
                log             true;
                executeControl      writeTime;
                writeControl        writeTime;
        }

Is there a kind of command like 'allRegion'?

Hi,

There is a new multiregion function object allowing to do this in the latest ESI-OpenCFD release (OpenFOAM-v2106) : https://www.openfoam.com/news/main-n...ng#multiregion
AFAIK, there is nothing similar in the older versions nor in the foundation branch, but I would be happy to know if somebody else has a solution for this.

As a workaround to save you a little bit of time, you can do something like this in order to avoid duplicating the function definition:

functions
{

    CellVolumeSteel
    {       
            // Mandatory entries (unmodifiable)
            type            writeCellVolumes;
            libs            (fieldFunctionObjects);
            
            // Optional (inherited) entries
            region            steel;
            enabled         true;
            log             true;
            executeControl    writeTime;
            writeControl    writeTime;
    }
    
    CellVolumeRegion2
    {
        $CellVolumeSteel
        region                region2;
    }
    
    ...
}

Another way around would be to write a script yourself to loop over all the regions and automatically generate the proper code. It could be worth spending to write such a script if you have a lot of regions in your case.

Cheers,
Yann

Hi,
thanks for this. It works like a charm with ESI Toolbox version2012. I have 3 regions. Therefore I don't think that I will code a loop


This new function is indeed quite useful. But I will have to adapt my custom solver to it.
