install openfoam in fedora

please i use fedora 12 and i want to install openfoam for my first time.

how can i install it ?
is fedora (bash or ksh) or (csh or csh)

to install gcc-4.3.3 read me file told me to
Install the compiler in:

$WM_PROJECT_INST_DIR/ThirdParty/gcc-<GCC_VERSION>/platforms/$WM_ARCH$WM_COMPILER_ARCH/
and change the gcc version number in $WM_PROJECT_DIR/etc/settings.sh and
$WM_PROJECT_DIR/etc/settings.csh appropriately and finally update the
environment variables as in section 3.
i don't understand this

1- what is $wm
2- where the compiler
:)

Hi Ahmed,

OpenFOAM can happily run on Fedora, no worries.

Download the right (i.e. 32 or 64 bit) packages from OpenCFD. If you don't know whether you have 32 or 64 bit linux, open up a terminal and type

Code:

uname -m

When you see "x86_64" it is 64 bit, when you see something like "i686" it is 32 bit.

Then, make a directory called "OpenFOAM" in your home directory

Code:

mkdir OpenFOAM

Put the downloaded files in the OpenFOAM directory and unpack them with

Code:

tar xzf OpenFOAM-1.6.General.gtgz

and so on for the other three files as well. It is important you unpack the packages labelled "General" first.
Now open up ".bashrc" in the home directory with

Code:

gedit ~/.bashrc

(don't forget the dot (".") before "bashrc") and add the line (again, don't forget the dot (".") at the beginning):

Code:

. $HOME/OpenFOAM/OpenFOAM-1.6/etc/bashrc

Finally, update the shell by (note the dots again)

Code:

. $HOME/.bashrc

That should do the trick. You can check the installation with

Code:

foamInstallationTest

Fedora uses a bash shell.

ThirdParty should come with a gcc compiler, but if you have the possibility it is better to build your own compiler. "$WM_PROJECT_INST_DIR" is the ~/OpenFOAM directory you created in the beginning. So, suppose you install gcc-4.3.3 on a 64 bit linux machine, then

Code:

$WM_PROJECT_INST_DIR/ThirdParty/gcc-<GCC_VERSION>/platforms/$WM_ARCH$WM_COMPILER_ARCH/

Code:

~/OpenFOAM/ThirdParty/gcc-4.3.1/platforms/linux64/

("~" means your home directory, your case perhaps /home/ahmed/). So that's the path you can put your new gcc in. Then, you need the make OpenFOAM aware of this by making sure that in the file $WM_PROJECT_DIR/etc/settings.sh the right version of gcc is exported. In settings.sh (on line 121 (I think :))) it reads something like

Code:

export WM_COMPILER_DIR=$WM_THIRD_PARTY_DIR/gcc-4.3.1/platforms/$WM_ARCH$WM_COMPILER_ARCH/gcc-4.3.1

Now, make sure that the version numbers (above "4.3.1") are the right numbers (i.e. change them to "4.3.3", if that is what you're using). Again, just do

Code:

gedit $WM_PROJECT_DIR/etc/settings.sh

fix the line and save. In Fedora you don't need to change settings.csh.

I guess the above should explain that.

2- where the compiler

It should live in $HOME/OpenFOAM/ThirdParty. The latest version you can get from the GCC website.

Hope this helps you on your way a bit!

Dear gwierink

Thank you very very much for your useful guides.
one question is that i couldn't install on home dir because of permission denied error so i install it on home/user dir. is that make problem later?

Hi maysmech,

You're very welcome, glad I could be of any help!

Quote:

i couldn't install on home dir because of permission denied error

That's not a problem, nor strange :). "$HOME" means "/home/maysmech" (if your user account is called "maysmech"). If you install OpenFOAM in "/home/" you're basically making a user called "OpenFOAM" where probably only root has write permission. In other words, you did the right thing by putting OF in your user directory :). Happy foaming!

thanks
i install it and when doing 1st tutorial, writing paraFoam this message is seen.

paraFoam -case $FOAM_RUN/tutorials/incompressible/icoFoam/cavity
created temporary 'cavity.OpenFOAM'
/home/maysam/OpenFOAM/ThirdParty-1.6/paraview-3.6.1/platforms/linux64Gcc/bin/paraview-real: error while loading shared libraries: libssl.so.0.9.8: cannot open shared object file: No such file or directory

i installed all 5 files in OpenFOAM website so why i cant see mesh at parafoam as written in tutorial pdf?

Hmm, have a look at this thread and this thread. There people had the same/similar problem and soft linked libssl.so.9.8 by

Code:

ln -s /usr/lib64/libssl.so.0.9.8k /usr/lib64/libssl.so.0.9.8

and/or

Code:

ln -s /lib64/libssl.so.0.9.8b /lib64/libssl.so.0.9.8 

ln -s /lib64/libcrypto.so.0.9.8b /lib64/libcrypto.so.0.9.8 

ln -s /usr/lib64/elfutils/libebl_x86_64-0.125.so /lib64/libelf.so.0

i used readme of openfoam site http://www.openfoam.com/docs/README.php#README

cd $WM_THIRD_PARTY_DIR
rm -rf paraview-3.6.1/platforms
makeParaView

The PV3FoamReader module is an OpenFOAM utility that can be compiled in the usual manner as follows:

cd $FOAM_UTILITIES/postProcessing/graphics/PV3FoamReader
./Allwclean
./Allwmake

now my error changes to:

/home/maysam/OpenFOAM/OpenFOAM-1.6/bin/paraFoam: line 129: paraview: command not found

Quote:

/home/maysmech/OpenFOAM/OpenFOAM-1.6/bin/paraFoam: line 129: paraview: command not found

Right, did you export the path to ParaView in .bashrc?

Code:

gedit $HOME/.bashrc &

and add

Code:

PATH= <path_to_paraview>:$PATH

export PATH

where <path_to_paraview> is your path to ParaView. In my case it is

Code:

PATH=/home/gijsbert/OpenFOAM/ThirdParty/ParaView3.3-cvs/platforms/linux64Gcc/bin:$PATH

export PATH

but at the moment I'm on a machine that only has 1.5-dev installed, so I can't check it at the moment :rolleyes:. Have a look where paraview lives on your system and add the right path. Then, don't forget to update the shell with

Code:

. $HOME/.bashrc

really i thank you for your reply and being patient with me.
thank you
:)

No worries, glad to help, you're welcome :). I also started as a beginner ;).

i find directories to paraview directory but not more because not same as your format!

/home/maysmech/OpenFOAM/ThirdParty-1.6/ParaView3.6.1

:( i changed the .bashrc (gedit $HOME/.bashrc &) to

Quote:

PATH=/home/maysam/OpenFOAM/ThirdParty-1.6/ParaView3.6.1-cvs/platforms/linux64Gcc/bin:$PATH
export PATH

and updating causes this output:

Code:

[maysam@maysam cavity]$ . $HOME/.bashrc

bash: id: No such file or directory

bash: id: No such file or directory

bash: grep: No such file or directory

now i type again gedit $HOME/.bashrc but the editiable .bashrc doesn't open and output is
bash: gedit: No such file or directory

:(

You have ParaView3.6.1, not 3.6.1-cvs, so remove the "-cvs" from the line you just added to .bashrc, save the file, do again

Code:

. $HOME/.bashrc

and see what happens ...

typing gedit $HOME/.bashrc the editiable .bashrc doesn't open and output is
bash: gedit: No such file or directory

i restart my system maybe it be solve but now i can not enter to fedora. i don't know what should i do.

No gedit :eek:? Hmm, that's weird ... Let's try vi:

Code:

vi $HOME/.bashrc

Then, type "i" for "insert mode", fix the line, type "ESC" (the ESCAPE key), and save and exit by ":wq" (notice the ":"). Then, type again

Code:

. $HOME/.bashrc

Does that work?

my problems increase exponentially;)

after restarting fedora i can't log in (after typing password nothing happen)
now i use windows

i think i should re install fedora and OpenFOAM and ...
i am worry this situation cause losing important data after doing some works on openfoam:confused:

Ai, that's nasty :(. Sorry to hear that! If your linux patition is completely dead, maybe it's an idea to access the data using a Knoppix live CD (since Windows (probably) can't access the data). Burn a Knoppix Live CD, reboot, and under Knoppix copy your stuff to a USB stick. Good luck!

hi again
i reinstall fedora and OpenFOAM.
typing paraFoam leads to previouse error.
i read this http://www.openfoam.com/docs/README.php#README
and my version of qt is 3.3.8b so i install a 35MB file that was there:
ftp://ftp.trolltech.com/qt/source/qt...-4.3.5.tar.bz2

i put and execute that and after that now my version is still previous.
what should i do?:(

Hi,

After you have compiled Qt-4.3.5 successfully, you need to make the shell aware of it. This is done by adding the path to the (new) qmake executable to your .bashrc file. In my case the compiled qmake lives in /home/gijsbert/tmp/qt-x11-opensource-src-4.3.5/bin, so I add the following:

Code:

PATH=/home/gijsbert/tmp/qt-x11-opensource-src-4.3.5/bin:$PATH

export PATH

So check out where your freshly compiled qmake lives and put your version of the above in your .bashrc. And of course you need to open a new terminal or reload the environment variables by

Code:

. $HOME/.bashrc

my problem was solved.:D
i update my Qt version by typing this command on terminal.

Code:

su -c 'yum update qt'

:)

Now paraView works.
thank you dear Gijsbert.
