I am a new user of Open foam and blockmesh. I tried to do the first tutorial : cavity.
When I want to generate the mesh I have this message :
cannot open file

file: /home/caelinux/Bureau/TEST_OF/cavity/constant/polyMesh/system/controlDict
at line 0.
From function regI0object::readStream(const word&)
in file db/regI0object/regI0objectRead.C at line 66.
FOAM exiting
I made an installation on USB-hard drive , it is possible that it is the origin of the error ?

Yes, it is likely that the usb install is the root of your error.

Openfoam is trying to find the controlDict at its typical location on the hard drive. Two possible solutions here:

1. Simply copy the entire tutorials directory to the hard drive in the location it is looking for it (directory structure should be quite similar). This will probably be the easiest, but might not work in certian cases.

2. Make sure your bashrc knows the where open foam is at. Read part 3 at this link:

I have used openfoam directly, so I am not certain if cea handles stuff differently or not.

Good Luck!

Just take a look at the location where the controlDict is being searched....

file: /home/caelinux/Bureau/TEST_OF/cavity/constant/polyMesh/system/controlDict
at line 0.

I would say you might get some results if you fire the application from the case directory and not the constant polyMesh directory...........

Hope this helps !!!!!!!!!!!!
