ok gijs, i think that just about did it!

Well at least i typed this in the terminal: . $HOME/.bashrc (should i type source instead of the period?)

And nothing happened, just a new line came, i think that is good. Now i have to run the foamInstallationScript.

And it worked!

Base configuration ok.

critical systems ok.

Thank you so much for your time gijs, and for your patience. I know it is hard, but you have no idea how much you have helped me!

Fantastic! That is good to hear, I am happy it works now! Happy foaming!

The dot and "source" are equivalent, so you can choose.

Yep, that's good, you're just making the shell aware of new environment variables (in this case that OF has its own bashrc and that it should be read).

Hi, I am installing OF-1.6 on Ubuntu 8.1.
I have extracted files successfully into the Home/<username>/OpenFoam/
But not able to source bashrc file.
Also from the comments of previous forum had confused me, which file to edit bashrc i n home location or from OpenFoam/OpenFOAM-1.6/etc location.
I m getting following msg after using source bashrc command..


bash: /home/iyer/OpenFOAM/OpenFOAM-1.6/bin/foamCleanPath: No such file or directory
bash: /home/iyer/OpenFOAM/OpenFOAM-1.6/bin/foamCleanPath: No such file or directory
bash: /home/iyer/OpenFOAM/OpenFOAM-1.6/bin/foamCleanPath: No such file or directory
bash: /home/iyer/OpenFOAM/OpenFOAM-1.6/etc/settings.sh: No such file or directory
bash: /home/iyer/OpenFOAM/OpenFOAM-1.6/etc/aliases.sh: No such file or directory
bash: /home/iyer/OpenFOAM/OpenFOAM-1.6/etc/apps/paraview3/bashrc: No such file or directory
bash: /home/iyer/OpenFOAM/OpenFOAM-1.6/etc/apps/ensight/bashrc: No such file or directory
bash: /home/iyer/OpenFOAM/OpenFOAM-1.6/bin/foamCleanPath: No such file or directory
bash: /home/iyer/OpenFOAM/OpenFOAM-1.6/bin/foamCleanPath: No such file or directory
bash: /home/iyer/OpenFOAM/OpenFOAM-1.6/bin/foamCleanPath: No such file or directory

plz help me

Hi Javed,

There are two bashrc files; one of OpenFOAM (that lives in ~/OpenFOAM/OpenFOAM-1.6/etc/) and one of your system (the user that is) (that lives in ~/.bashrc). Now, for a normal installation of OF (no compilation) you only need to change ~/.bashrc (notice the dot (".")) to make the shell aware of OF's environment variables. So, the recipe is as follows:
  1. Extract the files in the right location (which you seemingly already did)
  2. Open file ~/.bashrc
    Code:
    gedit ~/.bashrc &
  3. Add the line
    Code:
    . $HOME/OpenFOAM/OpenFOAM-1.6/etc/bashrc
    to file ~/.bashrc (notice the dot "." in the code to add)
  4. Save file ~/.bashrc
  5. Source the newly edited ~/.bashrc by
    Code:
    . $HOME/.bashrc
    (notice the dot again)

Thanks Gijs for the quick reply.
I followed the same procedure considering . in every single command. But still getting the error like

iyer@iyer-desktop:~$ . $HOME/.bashrc
bash: /home/iyer/OpenFOAM/OpenFOAM-1.6/etc/bashrc: No such file or directory

want to clear two things
1) i m editing ~/.bashrc file of system and typing the command . $HOME/.bashrc in my home directory (name-/home/iyer).
2) Should i run :/$ source OpenFOAM-1.6/etc/bashrc before editing bashrc file.

I need ur help. plz reply. Thanks

Ok, now things are getting a bit messy here . I'll try to explain what to do and why.

First, let's get some syntax clear:
  • "$HOME" is the same as "~"
  • "source" is the same as "."
  • "OF" means "OpenFOAM"

Now, the idea behind the "environment variable and sourcing" stuff is that OF has its own bashrc file, through which OF makes the shell (the terminal where you type and calculate stuff) aware of the different parts OF needs to run. There it is stated what C++ compiler to use, where it is, what ParaView to use etc. The thing is that you need to make your "own shell" (the terminal you open to type commands) aware of these rules for OF (stated in the $HOME/OpenFoam/OpenFOAM-1.6/etc/bashrc file). To do that, you do not need to change $HOME/OpenFoam/OpenFOAM-1.6/etc/bashrc, but you need to make $HOME/.bashrc aware of $HOME/OpenFoam/OpenFOAM-1.6/etc/bashrc. This is done by adding the line
Code:
. $HOME/OpenFoam/OpenFOAM-1.6/etc/bashrc
to $HOME/.bashrc and sourcing $HOME/.bashrc. The dot (".") at the start of the line to add is shorthand for "source". Every time you open up a terminal $HOME/.bashrc is sourced (kind of checked for rules). So, if you add
Code:
. $HOME/OpenFoam/OpenFOAM-1.6/etc/bashrc
to your $HOME/.bashrc, OF's "rules" are automatically sourced when you start a terminal. Then, the terminal recognizes OF commands like "foam", "run", "blockMesh" etc.

When you remove the line
Code:
. $HOME/OpenFoam/OpenFOAM-1.6/etc/bashrc
from $HOME/.bashrc and then source $HOME/.bashrc by
Code:
. $HOME/.bashrc
or
Code:
source $HOME/.bashrc
no erro is given because the shell doesn't care whether you source OF or not. It only complains when you write something wrong in it or something with the wrong path.

So, to make a long story short, do this:
Quote:
  1. Open file ~/.bashrc Code:
    gedit ~/.bashrc &
  2. Add the line Code:
    . $HOME/OpenFOAM/OpenFOAM-1.6/etc/bashrc
    to file ~/.bashrc (notice the dot "." in the code to add)
  3. Save file ~/.bashrc
  4. Source the newly edited ~/.bashrc by Code:
    . $HOME/.bashrc
    (notice the dot again)
Then, your two other questions.
Quote:
1) i m editing ~/.bashrc file of system and typing the command . $HOME/.bashrc in my home directory (name-/home/iyer).
Yes, you need to edit ~/.bashrc (which btw is the same as $HOME/.bashrc) and source ~/.bashrc. It doesn't matter "where" you do that, you don't have to be in your home dir. Alternatively, you could just close the terminal and open a new one. Then, ~/.bashrc is automatically sourced.

Quote:
2) Should i run :/$ source OpenFOAM-1.6/etc/bashrc before editing bashrc file.
No, you don't need to do that. This is what ~/.bashrc does for you when you source ~/.bashrc or open a new terminal, because you put the line ". $HOME/OpenFOAM/OpenFOAM-1.6/etc/bashrc" in ~/.bashrc. By the way, "OpenFOAM-1.6/etc/bashrc" is a relative path, that is it doesn't work from just any directory, but only when you are in the ~/OpenFOAM directory.



Quote:
iyer@iyer-desktop:~$ . $HOME/.bashrc
bash: /home/iyer/OpenFOAM/OpenFOAM-1.6/etc/bashrc: No such file or directory
Right, did you unpack OF in ~/OpenFOAM? If so, the path name is right and it looks like you actually deleted (or renamed) the file /home/iyer/OpenFOAM/OpenFOAM-1.6/etc/bashrc. If you have done that, please put it back into place (for the reason explained above).

Hope this clears up some things.

You're very welcome Javed, I'm glad it worked .

Well, to my knowledge, OF-1.4.1 had a GUI called FoamX, but OF-1.5 and later not anymore. It is better and more powerful IMHO if you learn command line. It may be a bit challenging in the beginning, but you'll learn.

I suggest you start with some tutorials in the user guide (lives in $HOME//OpenFOAM/OpenFOAM-1.6/doc) and then there are some nice tuts in the wiki.
