I would like to run refineMesh on an area that can be approximated by two boxes.

How do I define a cellSet in topoSetDict that includes the cells contained within these two boxes?

This should be a simple syntax issue, but my google-fu has failed me. Currently I have:

actions ( {
name c0;
type cellSet;
action new;
source boxToCell'
sourceInfo {
(x1 y1 z1) (x2 y2 z2);
}
}
)

I've been playing around in the setSet environment and the commands appear to function intuitively there. However, in topoSetDict, I'm still getting really irrational behavior.

cellset c0 new boxToCell (a b c) (d e f)
cellset c0 add boxToCell (g h i) (j k l)

functions perfectly well in setSet, but I have no idea how to translate this into something that topoSet will understand. I'm working in OF 2.3.

Does anyone have any recommendations?

The TL;DR solution for posterity is that OpenFOAM cares A LOT about white space.

boxToCell(a b c) (d e f);

is very different from

boxToCell (a b c) (d e f);
