I was doing this tutorial from don't remember where?, it went well but when I was starting to use the snappyHexMesh at first try this came up:

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

Patch    Type    Region
-----    ----    ------
sylinteri:

6    wall    sylinteri_region0

Added patches in = 0 s

Selecting decompositionMethod hierarchical


--> FOAM FATAL IO ERROR: 
keyword allowFreeStandingZoneFaces is undefined in dictionary "$FOAM_RUN/gridTutorial/system/snappyHexMeshDict::castellatedMeshControls"

FOAM exiting

I checked the snappyHexMeshDict but I couldn't find the keyword allowFreeStandingZoneFaces which is mentioned in the error, I have not used that. Any help?
