"No such file or directory exists" error

Hey guys!

Just installed OpenFOAM-3.0.0 in Ubuntu 14.04 in my PC. Then, I tried running the Lid Driven Cavity Flow tutorial. But this error keeps getting in the way and prevents the following line from getting executed on Terminal:

Code:

cd $FOAM_RUN/tutorials/incompressible/icoFoam/cavity

I keep getting this message when I execute the above line:
bash: cd: /tutorials/incompressible/icoFoam/cavity: No such file or directory

I checked the files in the directory and made sure they are in proper order. I've included the screenshot of the directory.

Can someone help me with setting this right?:confused:
Thanks

Quick answer: It seems like the OpenFOAM shell environment is not active. My guess is that you followed these instructions: https://openfoamwiki.net/index.php/I...u#Ubuntu_14.04
If you did, then whenever you start a new terminal you should run:

Code:

of300

If it doesn't work, please provide more details about which installation instructions you followed. Because if you followed the official instructions from source, you should run:

Code:

source $HOME/OpenFOAM/OpenFOAM-3.0.0/etc/bashrc
