Hello everyone,

I am trying to run some basic 2D rectangular geometry simulation, where I am using funkySetFieldsDict. Does anyone know what is the meaning of "zminus" in the below file.

FoamFile
{
    version         2.0;
    format          ascii;

    root            "/.automount/werner/Werner/bgschaid/bgschaid-foamStuff/DepositionTests";
    case            "neutralTest";
    instance        "system";
    local           "";

    class           dictionary;
    object          funkySetFieldsDict;
}

expressions
(
    pressureset1
    {
        field p;
                create 1;
        expression "10133";
        valuePatches ( zminus );
        dimension [1 -1 -2 0 0 0 0];
    }
    pressureset2
    {
        field p;
        expression "506625";
        condition "(pos().x <= 0.006*sin(pos().y*50*2*3.1415926+50*0.25*3.1415926)+0.01)  ";
        valuePatches ( zminus );
                keepPatches 1;
        dimension [1 -1 -2 0 0 0 0];
    }
    velocityset
    {
        field U;
                create 1;
        expression "vector(0,0,0)";
        valuePatches ( zminus );
        dimension [0 1 -1 0 0 0 0];
    }
    temperatureset1
    {
        field T;
                create 1;
        expression "300";
        valuePatches ( zminus );
        dimension [0 0 0 1 0 0 0];
    }
    temperatureset2
    {
        field T;
        expression "1800";
        condition "(pos().x <= 0.006*sin(pos().y*50*2*3.1415926+50*0.25*3.1415926)+0.01)  ";
        valuePatches ( zminus );
    }
);
