Summary0000920: Print stack error from surface sample functionObject and interFoam use in parallel
DescriptionLarge interFoam parallel jobs crash (tested on 600 cores) with a print stack error when a surface sample functionObject attempts to write. The sample function in the controlDict:

*****************************************************
    freeSurfaceElevation
    {
        type surfaces;
        functionObjectLibs ("libsampling.so");

        outputControl timeStep;
        outputInterval 5000;

        interpolationScheme cellPoint;

        surfaceFormat raw;
        fields (alpha1);
        surfaces
            (
             freeSurface
             {
             type isoSurfaceCell;
             isoField alpha1;
             isoValue 0.5;
             interpolate true;
             }
            );
    }
*****************************************************

The error:
#0 Foam::error::printStack(Foam::Ostream&)
Additional InformationNo issue with damBreak tests in serial.
TagsNo tags attached.

The writing triggers the construction of the iso surface. Do you get the same effect with a different type of surface ? (e.g. type 'patch')?

It could be that your master machine (that combines all the surfaces for writing) is not running out of memory. The iso surface might be huge on a complex field.

hi mattijs, this is a good point and probably the issue i am seeing. i do have to request large memory nodes for reconstruction and so it makes sense that the regular nodes would not have enough memory to create the rather significant iso surface. i did not connect the dots, thanks.
