Hi everyone, when I try to use snappyHexMesh on my imported STL file it seems to work well :

Overall mesh bounding box  : (-1 0 -1) (1 1 1)
Relative tolerance         : 1e-06
Absolute matching distance : 3e-06

Reading refinement surfaces.
Read refinement surfaces in = 0.01 s

Reading refinement shells.
Refinement level 2 for all cells inside cylinder.stl
Read refinement shells in = 0.01 s

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

Reading features.
Read edgeMesh cylinder.eMesh
    points      : 880
    edges       : 880
    boundingBox : (-20 -19.9938 -50) (51 19.9938 50)

Refinement level according to distance to "cylinder.eMesh" (880 points, 880 edges).
    level 1 for all cells within 0 metre.
Read features in = 0 s


Determining initial surface intersections
-----------------------------------------

Edge intersection testing:
    Number of edges             : 192500
    Number of edges to retest   : 192500
    Number of intersected edges : 0
Calculated surface intersections in = 1.12 s

Initial mesh : cells:62500  faces:192500  points:67626
Cells per refinement level:
    0	62500

Adding patches for surface regions
----------------------------------

Patch Type                Region                        
----- ----                ------                        
cylinder:

4     wall                cylinder                      

Added patches in = 0.01 s

Selecting decompositionMethod none

But then I receive this error message :

FOAM FATAL IO ERROR: 
keyword allowFreeStandingZoneFaces is undefined in dictionary "/home/maxime/postGeo/system/snappyHexMeshDict.castellatedMeshControls"

    From function const Foam::entry& Foam::dictionary::lookupEntry(const Foam::word&, bool, bool) const
    in file db/dictionary/dictionary.C at line 566.

I previously successfully applied blockMesh and surfaceFeatureExtract that gave me :

FOAM FATAL IO ERROR: 
keyword allowFreeStandingZoneFaces is undefined in dictionary "/home/maxime/postGeo/system/snappyHexMeshDict.castellatedMeshControls"

The blockMeshDict I'm using is :

Thanks in advance.
