Here are selected sections of my topoSetDict: (..trying to limit your eye-work..)

I've tried to make it as clear as possible. You will see two places where I delete cells with boxToCell. The second one works, the first one does not. The command-line output:


---------------


Reading "topoSetDict"

Time = 0
mesh not changed.
Created cellSet cs
Applying source cylinderToCell
Adding cells with centre within cylinder, with point1 = (0 0 -100), point2 = (0 0 100) and radius = 0.031
cellSet cs now size 269
Read set cellSet cs with size 269
Applying source cylinderToCell
Removing cells with centre within cylinder, with point1 = (0 0 -100), point2 = (0 0 100) and radius = 0.03
cellSet cs now size 22
Read set cellSet cs with size 22
Applying source boxToCell
Removing cells with center within boxes 1((-10 0 100) (100 100 -100))
cellSet cs now size 22
Read set cellSet cs with size 22
Applying source boxToCell
Removing cells with center within boxes 1((-100 -100 -100) (0 10 1))
cellSet cs now size 13
Created cellZoneSet solid
Applying source setToCellZone
Adding all cells from cellSet cs ...
cellZoneSet solid now size 13
End
[/CODE]


Notice that the cellSet size does not change for the first boxToCell. ..I'd include an image of the result, but it's on my computer, not online. There are cells that should be removed by the first box. ..I can prove this to you, if need be..

The coordinates of the box must always be lesser -> greater! so, well, exactly as the instructions say, xmin -> xmax, same for y, z.
