Installing OpenFOAM 1.5 on OpenSUSE 11.1
 

Hello everybody, I'm going directly to explain you my doubts.

I'm a newbie both in Linux and in OpenFOAM and I am having some troubles in trying to install this software on my new OS. I tried to follow the instructions pointed in albertopassalacqua's blog and in openFOAM's README file. Despite this, I don't understand how to manage the bash and bashrc configuration.

Moreover, I would like to ask you: I didn't put the OpenFOAM files in Home folder, but in the administrator inner one. Can this be a source of problems?

Hi,

You need to edit your ~/.bashrc file and add the following at the bottom:

. <path_to_your_OpenFOAM_directory>/OpenFOAM-1.5/etc/bashrc

Replace <path_to_your_OpenFOAM_directory> with your path.

Save the file, close the terminal, and open a new one.

Run the following command:

foamInstallationTest

and post here the output, if errors do exist.

Regards,
Jose Santos

The exact line to add to your

~/.bashrc

file is:

. $HOME/OpenFOAM/OpenFOAM-1.5.x/etc/bashrc

if you are using OpenFOAM 1.5.x from git.

Regards,
A.

When I execute foamInstallationTest, I obtain this error:

I don't know what else I have to do. Can someone help me?

Yes. The scripts assume you put the package in a directory called OpenFOAM in your home directory.

For a centralized installation see here, but it is quite useless if the machine is not shared with others: https://www.mfix.org/mwiki/index.php...l_Installation

Best regards,

I tried to follow every single instruction, but I still get in trouble. Now, I continue to receive the preceding by foamInstallationTest and when I "update the environment variables", I obtain this message:

I've read in the forum that this problem could be solved removing the # comment sign from the bashrc file. On the contrary, this line has been always uncommented, so I can't really understand where can be the problem with the installation.
Just to be clear in the passages I followed:

1. I downloaded the OpenFOAM-1.5.General.gtgz and ThirdParty.General.gtgz for Linu 32bit distributions;
2. I decompressed the program in /home folder as pointed out by the instructions reported in the website;
3. Finally I followed the instructions reported in the README file and still i can't move from the point in which I am trapped.

Please, HELP! :(

Install OpenFOAM as a user not root.

The installation instructions assume the install files are decompressed from an OpenFOAM directory in the user's home directory, i.e.,

/home/yourusername/OpenFOAM

not /home or /root. yourusername is your user name.

After decompressing, you should find directories

/home/yourusername/OpenFOAM/OpenFOAM-1.5
/home/yourusername/OpenFOAM/ThirdParty

Also, manually create a directory

/home/yourusername/OpenFOAM/yourusername-1.5

Another tip -- to check the setting for an environment variable varname use the command

echo $varname

Hope this helps.

Hi, this directory should actually be created automatically the first time you source openFOAM bash (or csh) configuration script. :)

Thank you very much gac, you gave me the chance to make a big step forward in the installation procedure. Now, what I get by foamInstallationTest is:

It seems to be an error relating to icoFOAM. The only operation I did was to take the thirdparty software and bring it inside the ThirdParty OpenFOAM directory. Have I to do some further steps?

Hi,

does icoFoam run on one of its tutorial (cavity, for example)?

P.S. You should update to 1.5.x so to get the bugfixes. To do this, use git (see the link you posted to my blog), and recompile OpenFOAM.

Best,

I updated the program to 1.5.x through the git repository, but now I obtain 2 errors instead of 1... :rolleyes: I show you the result of foamInstallationTest:

I really don't know what to do.

Moreover, when I try to run the "cavity" tutorial, I obtain these results:

News: I opened setting.sh (conteined within OpenFOAM/OpenFOAM-1.5.x/etc) and I changed the line "compilerInstall" from OpenFOAM to System. In this way my "critical error" (related to gcc) disappeared. So, I, at least, came back to the situation with just the icoFOAM issue.

This is my last openFoamInstallationTest report:

I went into OpenFOAM/OpenFOAM-1.5.x/applications/bin/linuxGccDPOpt and I realized that no files are present. What does this mean?

If you just downloaded OpenFOAM 1.5.x from the git repository, you still have to compile it, as explained in my blog post: http://albertopassalacqua.com/?p=260

Best,

Anyway, I dowloaded "Binary pack, double precision" software and I manually copied and pasted the included files within applications, lib and wmake. I don't know if this is the right procedure, but allowed me to repair the critical error relating to icoFoam (so, finally, no critical errors at all!).

Moreover, I had to install cmake libraries (required by Paraview) and then, I passed to the compiling process: well, it has been working from half an hour or more. :eek: I hope this is normal... :confused:

Hi,

well, if you are willing to follow, I can guide you through it step by step. It seems you are a bit lost. :)

To follow the steps, please, start from scratch, to be safe. From what you said in your last message, you mixed 1.5 and 1.5.x files.

The easy way to have a working and updated installation is the following:

• Create a directory called OpenFOAM in your home directory (not root).
• Open a terminal and enter the directory you have just created.
• Download the source code from the git repository with the command:

git clone git://repo.or.cz/OpenFOAM-1.5.x.git

• Download only the ThirdParty packages (both binary and source) from the OpenCFD website.
• Extract the ThirdParty packages, and copy it in your /home/username/OpenFOAM directory.
• Open the file ~/OpenFOAM/ThirdParty/ParaView3.3-cvs/CMakeLists.txt and comment the lines:

MESSAGE(SEND_ERROR “Qt ${QTVERSION} not supported. Please use Qt 4.3 (you may need to clean your dirtied cache).”)

• Open your ~/.bashrc file and add the following line:

. $HOME/OpenFOAM/OpenFOAM-1.5.x/etc/bashrc

• Compile paraview and its reader following the instructions provided in OpenFOAM 1.5.x README file:

1. • cd $FOAM_INST_DIR/ThirdParty
   • rm -rf ParaView3.3-cvs/platforms
   • buildParaView3.3-cvs
   • cd $FOAM_UTILITIES/postProcessing/graphics/PV3FoamReader
   • ./Allwclean
   • ./Allwmake

• Compile OpenFOAM 1.5.x with ./Allwmake in its main directory

Depending on the machine you are using, it might take some time.

Let me know if you get it working.

Best,

I tried to follow as most as I could your instructions, but I still have some troubles. The compilation of ParaView is perfect, without any sort of mistakes in the log. On the contrary, in the installation of the reader, I received a certain amount of errors, that you can see after here:

During the compilation of OpenFOAM itself, I then realize that the process does not work at all and I obtain several times the same error in which I have "undefined reference to 'foam" and something else.
I looked around the forum and it seems to be related to libPstream.so. In fact, I typed this command:

and I had this result:

The reader builds. You reported warnings, if I did not miss something.

Could you give more details about the errors you read when you compile OpenFOAM?

Are you using a 64 bit distribution? Have you _all_ (binary and source) the third party packages installed? libPstream should be in

/home/Sam/OpenFOAM/OpenFOAM-1.5.x/lib/linux64GccDPOpt/openmpi-1.2.6/libPstream.so

if you have a 64 bit system, and something like that for a 32 bit version (linux instead than linux64 in the path).

Best,

I get a collection of errors like this one:
