Hi
I installed the debian pack of openfoam1.6-ext based on the instructions on openfoamwiki on Ubuntu 10.04. After I add alias in .bashrc and run startOF16ext it says that :
bash: /opt/OpenFOAM-1.6-ext/bin/foamEtcFile: No such file or directory
bash: /opt/OpenFOAM-1.6-ext/bin/foamCleanPath: No such file or directory
bash: /opt/OpenFOAM-1.6-ext/bin/foamCleanPath: No such file or directory
bash: /opt/OpenFOAM-1.6-ext/bin/foamCleanPath: No such file or directory
bash: /opt/OpenFOAM-1.6-ext/etc/settings.sh: No such file or directory
bash: /opt/OpenFOAM-1.6-ext/bin/foamCleanPath: No such file or directory
bash: /opt/OpenFOAM-1.6-ext/bin/foamCleanPath: No such file or directory
bash: /opt/OpenFOAM-1.6-ext/bin/foamCleanPath: No such file or directory

There's no file named by OpenFOAM-1.6-ext in opt directory. Besides I have installed another versions of OpenFOAM 2.0.1 and OpenFOAM 2.1.0.
What's the problem?
I appreciate any help...
Thanks

type

which icoFoam

to see whether you install OpenFOAM-1.6-ext or not?

Also it should be noted OpenFOAM-1.6-ext is not placed in /opt directory, as i remember (im not sure) it should be in /usr

[mary mor]

Thanks for reply
openfoam 2.1.0 has been installed.
Yes it exists in /usr/lib directory, but after I want to call it from terminal it gives the errors I mentioned in my previous post. It seems it hasn't been installed.

Doesn't it need to run wmake or anything else? The instruction says it's enough to add alias... to .bashrc

Greetings to all!

It would come in handy which exact steps you've taken to create said alias. And if you created aliases for the other OpenFOAM versions as well?

In addition, have you started a new terminal after installing 1.6-ext?

For more information, I suggest the following blog post: Advanced tips for working with the OpenFOAM shell environment

Hi Bruno,
As I mentioned, I followed the instructions in openfoamwiki,installation of debian pack linked by below:
http://openfoamwiki.net/index.php/In...ucid_10.04_LTS

For 1.6ext verision i added :alias startOF16ext="source /usr/lib/OpenFOAM-1.6-ext/etc/bashrc" to the end of line.

As well for OpenFoam2.1.0 I added . opt/openfoam210/etc/bashrc and it works.

And yes. I started a new terminal after installing! How can I check that it has been installed?!

Thanks,
Best Regards

[wyldckat]

Hi Maryam,

Uhm... OK. So I'm guessing you have something like this at the end of your "~/.bashrc" file:

. /opt/openfoam210/etc/bashrc
alias startOF16ext="source /usr/lib/OpenFOAM-1.6-ext/etc/bashrc"

Change it to this:

alias startOF210="source /opt/openfoam210/etc/bashrc"
alias startOF16ext="source /usr/lib/OpenFOAM-1.6-ext/etc/bashrc"

You will need a new terminal window whenever you want the other OpenFOAM version. For example:

• To use OpenFOAM 1.6-ext, start a new terminal and run:
  

  startOF16ext

• To use OpenFOAM 2.1.0, start a new terminal and run:
  

  startOF210

Best regards,
Bruno

[mary mor]

thanks Bruno, I changed the code as you said.
Now after entering startOF16ext it says:
/usr/lib/gcc/i486-linux-gnu/4.4.3/../../../../lib/crt1.o: In function `_start':
(.text+0x18): undefined reference to `main'
collect2: ld returned 1 exit status

(.text+0x18): undefined reference to `main'
collect2: ld returned 1 exit status

and when I try to run 2.1.0 version it gives the same error! as in my post #1:
bash: /usr/lib/openfoam210/bin/foamEtcFile: No such file or directory
bash: /usr/lib/openfoam210/bin/foamCleanPath: No such file or directory
bash: /usr/lib/openfoam210/bin/foamCleanPath: No such file or directory

That's strange... which Ubuntu version and architecture do you have?
You can check by running:

uname -m
cat /etc/lsb-release

[mary mor]

I started a new terminal
I don't know what happened by I once changed the line alias startOF210="source /opt/openfoam210/etc/bashrc" to alias startOF210='. /opt/openfoam210/etc/bashrc" and ran the terminal again and the following happened:

maryam@maryam-desktop:~$ startOF210
/usr/lib/gcc/i486-linux-gnu/4.4.3/../../../../lib/crt1.o: In function `_start':
(.text+0x18): undefined reference to `main'
collect2: ld returned 1 exit status

maryam@maryam-desktop:~$ startOF16ext
bash: /opt/OpenFOAM-1.6-ext/bin/foamEtcFile: No such file or directory
bash: /opt/OpenFOAM-1.6-ext/bin/foamCleanPath: No such file or directory

bash: /opt/OpenFOAM-1.6-ext/bin/foamCleanPath: No such file or directory
bash: /opt/OpenFOAM-1.6-ext/bin/foamCleanPath: No such file or directory

and the same is happening when I changed to the one you mentioned for alias.


I'm using Ubuntu 10.04.3 LTS lucid i686.

What does this give you?

tail ~/.bashrc

[mary mor]

sorry for late answer. It was time for bed and then university!

It says"

# enable programmable completion features (you don't need to enable
# this, if it's already enabled in /etc/bash.bashrc and /etc/profile
# sources /etc/bash.bashrc).
if [ -f /etc/bash_completion ] && ! shopt -oq posix; then
. /etc/bash_completion
fi

alias startOF210="source /opt/openfoam210/etc/bashrc"
alias startOF16ext="source /usr/lib/OpenFOAM-1.6-ext/etc/bashrc"

Maryam

Hi Maryam,

I've finished installing the same packages on a virtual machine with an up-to-date Ubuntu 10.04 i686 and I do not get the same error as you do.

But I suspect I know what the problem really is. Run the following command:

ls -l $(which mpicc) /etc/alternatives/mpicc

It should show you this:

lrwxrwxrwx 1 root root 22 2012-09-28 15:10 /etc/alternatives/mpicc -> /usr/bin/mpicc.openmpi
lrwxrwxrwx 1 root root 23 2012-09-28 15:10 /usr/bin/mpicc -> /etc/alternatives/mpicc

If it does not show you this, then that is the reason why you're getting these problems.

Best regards,
Bruno

[mary mor]

Hi Bruno,
It says:

lrwxrwxrwx 1 root root 21 2013-10-19 16:29 /etc/alternatives/mpicc -> /usr/bin/mpicc.mpich2
lrwxrwxrwx 1 root root 23 2013-10-19 16:30 /usr/bin/mpicc -> /etc/alternatives/mpicc

I have mpicc.mpich2 instead of you having mpicc.openmpi. Is this the problem?

Best regards,
Maryam

[wyldckat]

Hi Maryam,

In theory, yes, that's the problem. Do you need MPICH2 or can it be switched to Open-MPI as the default MPI?

Best regards,
Bruno

[mary mor]

Hi Bruno,
No I don't need it.But I don't know how to change it.

Besides I have another question. Does the debian pack have any difference with source installation? If not why it is said in wiki that debian installation is better for beginners?

The svn and git seems not to work. So can I use the openfoamwiki.net instruction at http://openfoamwiki.net/index.php/In...1.6-ext/Ubuntu or not?
If not from which repository I should use?
Sorry for asking too much...

Best regards,
Maryam

Well, it's better for beginners, if they have not already installed other software first
And if they have, it's sort-of assumed they have some experience with that other software.


Let's try taking care of fixing this problem with MPICH2. If it doesn't work, then you can try building from source.

OK, it's fairly simple. Run this command:

sudo update-alternatives --set mpi /usr/lib/openmpi/include

Now start a new terminal and try one of the alias commands, namely startOF16ext or startOF210.
Do not forget that you can only use 1 of these alias commands per terminal window!!


If later on you want to switch back to MPICH2 (quoting http://stackoverflow.com/a/18728955), run:

sudo update-alternatives --set mpi /usr/include/mpich2

Best regards,
Bruno

[mary mor]

Yesss. It doesn't give any error, now. Thanks so much.

But I have another problem!
How can I get access to solvers and tutorial files It's different with the other version I had previously

Thanks for your patiance...

Best regards,
Maryam

[wyldckat]

Hi Maryam,

Run:

echo $FOAM_TUTORIALS
echo $FOAM_SOLVERS

And those two lines should tell you where they are.

For more, try:

export | grep FOAM

Best regards,
Bruno

[mary mor]

Thanks Bruno
Yes I found the solvers folder but when I run echo for tutorials it says:
/usr/lib/OpenFOAM-1.6-ext/tutorials

But there's no such a folder in this directory. when I run : ls -a It doesn't show there's a tutorials folder

Maryam

Hi Maryam,

Sorry, I forgot that the 1.6-ext available in the PPA has a very restructured installation, with some missing parts.

Almost 2 years ago I wrote this:

Have a look in that folder. And if it's not in that folder, check this post: http://www.cfd-online.com/Forums/ope...tml#post330283 post #44.
