Hi!! I am new to OpenFOAM, and I want to get it set up before the beginning of next semester. I am following the instructions on:
http://www.openfoam.org/archive/2.1....oad/ubuntu.php

It seems to be going well, until I have to modify the bashrc file, since I can't open it from the terminal, and if I open it manually, I'm not able to add the line "source /opt/openfoam211/etc/bashrc" at the end of the file (saying I don't have permission to do so).

ruben@ruben-VirtualBox:~$ VERS=$(lsb_release -cs)       
ruben@ruben-VirtualBox:~$ sudo sh -c "echo deb http://www.openfoam.org/download/ubuntu $VERS main > /etc/apt/sources.list.d/openfoam.list"
ruben@ruben-VirtualBox:~$ sudo apt-get update
