CFD Online Discussion Forums - installation and tutorials

Hello.

I am a complete OpenFOAM novice, and would kindly like to ask a question regarding installation and usage of openFOAM.

I installed openFOAM using a pre-compiled .dmg and setup_foam.sh file (http://www.ifd.mavt.ethz.ch/educatio...foam/of-macosx). I created a directory ~/OpenFOAM/images/ so to avoid having to change any of your scripts. I then issued the commands, and setup_foam, and it apparently works. Here is the message:

Francesco-Ferronis-MacBook-Pro:~ MacbookPro$ setup_foam
expected CRC32 $CC188D9D
/dev/disk1 Apple_partition_scheme
/dev/disk1s1 Apple_partition_map
/dev/disk1s2 Apple_HFSX
/Users/MacbookPro/OpenFOAM/OpenFOAM-1.7.x
/dev/disk2 GUID_partition_scheme
/dev/disk2s1 EFI
/dev/disk2s2 Apple_HFS
/Users/MacbookPro/OpenFOAM/MacbookPro-1.7.x

From this, I get a OpenFOAM_1.7.x and a MacbookPro-1.7.x image on my Desktop. The MacbookPro-1.7.x is EMPTY. (Is this normal?)

As I'm a novice, predictably I went to try out a few tutorials (i.e. the cavity flow http://www.openfoam.org/docs/user/cavity.php#x5-40002.1). The first command it says to issue is:

cd $FOAM_RUN/tutorials/incompressible/icoFoam/cavity

However, running this prompt via Terminal.app, I get that there is no such file or directory. So perhaps it is something wrong with my installation or am I being a complete tit about something else?

Thank you again,

Kind Regards,

Francesco
