Hello experts,

I am new to the subject and I am quite confident that i messed up a lot in the snappyhexmeshDict and preprocessing, however I fail to learn anything from the error message that the mesher throws.
When I run

mpirun -np 4 snappyHexMesh -overwrite -parallel

it finally ends up here (snippet of output)

Splitting mesh at surface intersections
---------------------------------------

Introducing baffles for 0 faces that are intersected by the surface.

Edge intersection testing:
    Number of edges             : 4156674
    Number of edges to retest   : 0
    Number of intersected edges : 0
Created baffles in = 1.02 s


After introducing baffles : cells:1315931  faces:4156674  points:1544788
Cells per refinement level:
    0    990057
    1    60188
    2    139014
    3    126672

Introducing baffles to block off problem cells

the complete log is attached. Can anyone point me to the source of the problem?
I use OpenFoam 2.3.0 on Ubuntu Linux.

All the best,
