well, you may want to add surfaceFeatureExtractDict to your system folder, and edit it appropriately

Hi again,

I'm sorry to bother you again but it's not working. I edit the surfaceFeatureExtractDict, it takes care of 3 .STL files but still the same error : " FOAM FATAL ERROR :
Wrong number of arguments, expected 0 found3
Invalid option: -includedAngle

FOAM exittimg"

Best Regards,

Dadou

I just figured out the problem.
I'm using OpenFOAM 2.2.2 and the option -includedAngle doesn't exist anymore. You just have to write surfaceFeatureExtract and you will have your extrudeMesh.

I'm totally unfamiliar with snappyHexMesh commands if I have run it mistakenly.

.................I have been facing a similar problem and for the same problem for airfoil, where the command line returns:
--> FOAM FATAL ERROR:
Wrong number of arguments, expected 0 found 3
Invalid option: -writeObj
Invalid option: -includedAngle

Please could you share the solution to this problem with me??

Dear ehsan, thank you very much for your kind attention.:)
i put in the attachment the airfoil_snappyHexMesh_modified2 , please open the allrun in this folder, i write in it that you just should run blockMesh and after that snappyHexMesh in two steps as you see in the allrun.txt.

you should define the surfaceFeatureExtractDict in system folder, then run the command surfaceFeatureExtract on terminal.
There is no need for extra options.
