surfaceFeatureExtract fails - What's the problem?

I am trying to run part 1 of the attached case:
Part 1 as I call it does the following (Allrun script):
# Make 3D mesh in slab of cells.
blockMesh > output/1-blockMesh.log 2>&1
surfaceFeatureExtract -includedAngle 150 -writeObj constant/triSurface/airfoil.stl airfoil > output/2-surfaceFeatureExtract.log 2>&1
snappyHexMesh -overwrite > output/3-snappyHexMesh.log 2>&1
rm -f 0/*
The error log says:
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //
Create mesh for time = 0

Reading refinement surfaces.

Reading refinement shells.
Refinement level 2 for all cells inside refinementBox

Setting refinement level of surface to be consistent with shells.

--> FOAM FATAL IO ERROR:

From function regIOobject::readStream()
in file db/regIOobject/regIOobjectRead.C at line 73.
I can't find the error. What's the problem?

The problem is that you are using OpenFOAM 2.2, and the case you are running is made for 2.1. The way surfaceFeatureExtract is called has changed, in 2.1 all arguments were given on the command line, while in 2.2 it is given in the file system/surfaceFeatureExtractDict.
Since it is surfaceFeatureExtractDict that is generating airfoil.eMesh, snappyHexMesh fails because this file is missing. However the error lies in surfaceFeatureExtractMesh.
BTW: I see that you are running the case found here: https://www.hpc.ntnu.no/display/hpc/...l+Calculations This case should now be updated such that it works on both 2.1 and 2.2. If you download it again, it should work out-of-the-box. If not, please send me a PM.
