Hi,

I try to set environment variable for OpenFOAM 2.0.1 in CAE Linux 2011 which is Ubuntu 10.04 LTS. I try to accurately follow the instructions according to OpenFOAM pages but I am not able to create functional environment variable for OpenFOAM.

I have used instructions as follows:

In order to use the installed OpenFOAM package, complete the following

1. Open the .bashrc file in the user’s home directory in an editor, e.g. by typing in a terminal window (note the dot) gedit ~/.bashrc
2. At the bottom of that file, add the following line (see Note 1) and save the file source /opt/openfoam201/etc/bashrc
3. Open a new terminal window (see Note 2) and test that the icoFoam application, from the OpenFOAM package, is working by typing icoFoam -help

But without any help. Please help me and thanks in advance.

Greetings Tommi and welcome to the forum!

A quick question: did you install OpenFOAM 2.0.1 from OpenFOAM's website, or are you using the installation already provided with CAELinux?

Best regards,
Bruno

The OpenFOAM 2.0.1. is a default installation what came within the CAE Linux. The installation is fresh except I removed open java and installed Sun Java 8 to my Ubuntu.

Unfortunately I don't a CAELinux installation at hand, but according to this post of mine: http://www.cfd-online.com/Forums/ope...tml#post376326 post #26 - it looks like that CAELinux provides OpenFOAM 2.1.0?

Try these two commands:

ls -l /opt/openfoam201
ls -l /opt/openfoam210

Do any of them give any information?

Hi,

The OpenFOAM 2.0.1 is present but 2.1.0 is not. I have tried to install 2.1.0 but the problem was same...no environments set.

Here is the result of the command ls -l /opt/openfoam201:

total 84

drwxr-xr-x 6 root root 4096 2011-10-09 16:09 wmake

And the command ls -l /opt/openfoam210 gave this:

ls: cannot access /opt/openfoam210: No such file or directory

I tested the installation DVD with a md5 testers just for fun. There were no errors in the installation disk.

I also run:

./foamInstallationTest

and I got this kind of result in Ubuntu:

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.

Hi Tommi,

CAE Linux was designed to make it easier for people to use the software provided with it. Therefore, at the very least, they provide the following capabilities for using OpenFOAM:

• You can start a terminal with OpenFOAM ready to use, if you go to the main menu and choose the item at "Applications -> CAELinux -> OpenFOAM Terminal".
• Or from a standard terminal, run:
  

  source /opt/.bashrc-OpenFOAM

I've tested this on both the installed version and the DVD Live version.

Best regards,
Bruno

Hi,

I just wonder why it says that environment variable is not set when I test it. Is it somehow unusable command in Ubuntu?

I tested this OpenFoam terminal with

icoFoam -help

It give me output as follows:

Usage: icoFoam [OPTIONS]
options:
-case <dir> specify alternate case directory, default is the cwd
-noFunctionObjects
do not execute functionObjects
-parallel run in parallel
-roots <(dir1 .. dirN)>
slave root directories for distributed running
-srcDoc display source code in browser
-doc display application documentation in browser
-help print the usage

Using: OpenFOAM-2.0.1 (see www.OpenFOAM.com)
Build: 2.0.1-51f1de99a4bc

Everything seems to be ok from this point of view? Many thanks for help.

[wyldckat]

The OpenFOAM 2.0.1 installation provided in CAE Linux was done from the Deb packages that are provided at openfoam.org, which is why foamInstallationTest doesn't work.

This is because the foamInstallationTest script was created for testing the environment where OpenFOAM is built by the user and therefore doesn't work on pre-built installations.

Dear Tommy,

CAELinux is configured with a special terminal for OpenFOAM. You will find it under Applications -> CAELinux .
You have to open this terminal to have the environment correctly configured.

Franco
