This is how an omega looks like inside a processor folder. For example, look at INTEROUTT2. What does nonuniform 0(); mean?

internalField   uniform 0.55;

boundaryField
{
    FARFIELD
    {
        type            fixedValue;
        value           nonuniform 0();
    }
    OUTLET
    {
        type            zeroGradient;
    }
    BODY
    {
        type            fixedValue;
        value           nonuniform 0();
    }
    INTEROUTT2
    {
        type            cyclicAMI;
        value           nonuniform 0();
    }
    INTEROUT2
    {
        type            cyclicAMI;
        value           nonuniform List<scalar>

nonuniform 0(); means that the boundary value are not uniform but the boundary patch is not present at the processor you are looking at.
