[Carpet] missing data for grid component

[Giovanni Corvino]

Hi, I have a problem with a compnent of my grid.

I'm running with 2 refinement levels like

[ [ ([-40.0,-40.0,0.0]:[40.0,40.0,18.0]:[1,1,1]) ],
 [ ([-30.0,-30.0,0.0]:[30,30,8]:[0.5,0.5,0.5]) ] ]"

the outer boundary is at 50 (bitant symmetry).

First of all I get the following warning while generating the initial
conditions:

INFO (Carpet): Recomposing the grid hierarchy for map 0...
Not properly nested: rl=1, required distance=4
Received from level 0:

Overlap on level 1:
bboxset<CCTK_INT4,3>:size=13994,setsize=5,set={([36,36,8]:[38,164,32]:[2,2,2]),([40,36,8]:[164,38,32]:[2,2,2]),([162,40,8]:[164,164,32]:[2,2,2]),([40,162,8]:[160,164,32]:[2,2,2]),([40,40,30]:[160,160,32]:[2,2,2])}


and then wheh I look at the data I see that one or more of the
components of the grid has not been computed, on all refinement levels.
Sometimes is only one component, sometimes two. What can it depend on?
Caould it be something tied to the boudary conditions of the boxes?

Thanks, Giovanni Corvino
