Default moving rotor AMI

Hello,

New to OF, I successfully ran this tutorial [1] with minor modifications for OpenFOAM-v1612+.
Now, I'm trying to build a similar case using my propeller instead of the rotor. My first goal is to check the moving mesh.

If I use the following parameters in sHM, createPatch gives result1_AMI containing result1_movingWall. The AMI is incorrect, which is normal.
castellatedMeshControls
{
...
maxLocalCells 24000;
maxGlobalCells 48000;
...
}
If I slightly increase the values, createPatch gives result2. The AMI seems correct but my propeller disappeared.
castellatedMeshControls
{
...
maxLocalCells 24375;
maxGlobalCells 48750;
...
}

Did I miss something ?

The problem did not come from createPatch but from the STL given to sHM.
I rebuilt the propeller in salome.
Next step is to refine the propeller.
