Some problems about using snappyHexMesh
 
Hello everybody,
I just started to use snappyHexMesh and tried to test some existed applications in OpenFOAM-2.1.0 to be familiar with the use of snappyHexMesh.
The directory is "./tutorials/incompressible/simpleFoam/turbineSiting/". I run some commands according to "Allrun". Firstly "blockMesh", then "cp system/decomposeParDict-nonPar system/decomposeParDict", then "decomposePar", then "cp system/decomposeParDict-par system/decomposeParDict", then "mpirun -np 2 snappyHexMesh -parallel -overwrite". The execution didn't finish and got stuck as below:

Create time

Create mesh for time = 0

Read mesh in = 0.23 s

Overall mesh bounding box : (581321 4785370 930) (582290 4786240 1500)
Relative tolerance : 1e-06
Absolute matching distance : 0.00142153473401

Reading refinement surfaces.
Read refinement surfaces in = 0.11 s

Reading refinement shells.
Refinement level 6 for all cells inside windTurbine1
Refinement level 6 for all cells inside windTurbine2
Read refinement shells in = 0 s

Setting refinement level of surface to be consistent with shells.
Checked shell refinement in = 0 s

Reading features.
Read features in = 0 s


Determining initial surface intersections

Edge intersection testing:
Number of edges : 56100
Number of edges to retest : 56100



Obviously the execution didn't finish. Does anyone know how to solve this problem? Thank you!

sorry misread the bounding box..

why is it so far from the origin?
