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:

Number of edges to retest : 56100



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