environment variables- CAE Linux

For OpenFOAM on CAE Linux platform, how do I configure the environment?

e.g. adding the following line to $HOME/.bashrc does not work

. $HOME/OpenFOAM/OpenFOAM-2.0.1/etc/bashrc

I tried changing the path to opt/openfoam201/etc/bashrc,
but then sourcing by

. $HOME/.bashrc

does not do anything.

I would really appreciate any help on this.

Greetings kal and welcome to the forum!

Edit your "$HOME/.bashrc" file and add this line (or modify the line you added to this):

Code:

. /opt/openfoam201/etc/bashrc

edit: I forgot to mention that you can also execute this line directly on the terminal window.

Good luck!

Thanks for your reply! I tried to put the line you suggested in the bashrc file, save, and execute . $HOME/.bashrc.
However, when I run foamInstallationTest, I still get the error that the OpenFOAM environment is not configured. This is how it looks like:

neha@neha:~$ gedit ~/.bashrc
neha@neha:~$ . $HOME/.bashrc
neha@neha:~$ foamInstallationTest
Executing /opt/openfoam201/bin/foamInstallationTest:

Checking basic setup...
-------------------------------------------------------------------------------

FATAL ERROR: OpenFOAM environment not configured.

Please refer to the installation section of the README file:
<OpenFOAM installation dir>/OpenFOAM-2.0.1/README
to source the OpenFOAM environment.

Please let me know if you can figure out what the error is from this.
Thanks again!

Hi kal,

The script foamInstallationTest was designed for source builds only and will not work for the Deb and RPM packages. In CAE Linux, it used a Deb package, so that is why it doesn't work.

The standard test is to run:

Code:

icoFoam -help

If it shows the help instructions for icoFoam, then it's working. You can see this information here: http://www.openfoam.org/download/ubuntu.php - section "User Configuration".

Best regards,
Bruno
