Dear all,

I have recently installed (compiled) OpenFOAM 4 on ubuntu 16.0.4 LTS successfully and it was working very fine.

In my .bashrc file I had created an alias as below:

alias of4c='source /opt/openfoam4Com/OpenFOAM-4.0/etc/bashrc'

Today when I execute the of4c in order to use OpenFOAM 4, I got the following lines in the terminal:

/home/m
_foamSource: command not found
_foamEval: command not found
_foamSource: command not found
_foamSource: command not found
_foamSource: command not found
_foamSource: command not found
_foamSource: command not found
_foamSource: command not found
_foamSource: command not found
/home/m



I am very amazed! because it was working fine just till yesterday!. I have no idea what has went wrong.

Could you please give advice?

Thanks,
Matt

Quick questions:

1. Is "/opt/openfoam4Com" a real path or a symbolic path?
2. Did you start a new terminal before running of4c?
3. When you start a new terminal and run the following command:
   

   export | grep -e FOAM -e WM

   does it give you any textual output?
   • If it does, then it's likely you have another OpenFOAM version or fork being loaded automatically and it's conflicting with the current installation.

Hi Bruno,

Thanks for your response.

Here are the answers to your questions:
1. /opt/openfoam4Com is a real path
2. Yes
3. This is the output of the results:

Indeed I have different versions (2 installations) of OpenFOAM installed in /opt folder. I read that it is possible to choose different versions of OpenFOAM through defining alias commands in the .bashrc file as below:

alias of4='source /opt/openfoam4/etc/bashrc'
alias of4c='source /opt/openfoam4Com/OpenFOAM-4.0/etc/bashrc'

How should I make sure that these versions are not conflicting with each other?

Thanks,
Matt

Hi Matt,

My apologies for the delay in getting back to you on this, but unfortunately flew by and I still haven't managed to deduce a solution or reasoning for this... wait... there were some recent details that came up which might explain this. I've documented some of them here: http://bugs.openfoam.org/view.php?id=2311

Technically I don't see anything in the output of export that would point to the problem with "GREP_OPTIONS", so that shouldn't be it... oh, wait, I asked you to run export with grep, so the output isn't complete.

OK, anyway, if you haven't fixed this already, let's try fixing this the other way around:

You can change those lines to this:

alias of4='[ -n "$WM_PROJECT_DIR" ] && source $WM_PROJECT_DIR/etc/config.sh/unset; source /opt/openfoam4/etc/bashrc'
alias of4c='[ -n "$WM_PROJECT_DIR" ] && source $WM_PROJECT_DIR/etc/config.sh/unset; source /opt/openfoam4Com/OpenFOAM-4.0/etc/bashrc'

Start a new terminal command line and it should be fully operational.
What I've done here is embed the command used by the alias "wmUnset", which you can see by running:

alias wmUnset

which gives:

alias wmUnset='. $WM_PROJECT_DIR/etc/config.sh/unset'

Now, you mentioned that this problem was recent (well, a month ago it was recent), then perhaps the "/bin/sh" shell was replaced? What do you get when you run these commands?

ls -l /bin/sh
ls -l /bin/bash
which sh

Best regards,
Bruno
