Greetings Hemanth and welcome to the forum!

I'm sorry to say that the OpenFOAM 2.4.0 Deb packages are not available for the ARM architectures.

The closest I know about people being able to build/install OpenFOAM on ARM7 architectures have been these two:

• http://www.cfd-online.com/Forums/ope...processor.html
• http://rheologic.at/?q=downloads&language=en
• http://www.cfd-online.com/Forums/ope...dison-bbb.html
• http://www.cfd-online.com/Forums/ope...model-2-a.html

Best regards,
Bruno

[Hemanth]

Thanks Bruno for the reply. Glad to know at least there are two people who installed openfoam on armv processer.

I have goen through the first link and the conversation. I didn't clearly understand all the instructions.

I am not knowing where to start and what to do.

Pelase help me with the procedure to modify the things as per Jon Elvar Wallevik suggested.

Any ways i will try doing some thing and mean while, i tried installation from source pack I got some error for which i am attachng the log file. Please help me with this if this problem is easy to fix.

[wyldckat]

Quick answer:

1. Run these commands:
   

   gcc --version
   g++ --version

   and let me know what each command gives you.
2. Then run these commands:
   

   foam
   ./Allwmake > log.make 2>&1
   gzip < log.make > log.make.gz

   And attach the file "log.make.gz" in your next post.

Here is log file. It shows the directory is not available because i deleted OpenFOAM folder. If you want me to compile again i will do that. Can you please send detailed instructions if available to install openfoam in ARM architecture.

Thanks in advance and in the rhelogical site i didnt understand which version to download and how to install.
Please help.

Hi Hemanth,

Sorry for the late reply, but only today did I finally manage to take a quick look into this.

If you're trying to install OpenFOAM 2.4.0 on a RaspberryPi 2, then you might want to check this post: http://www.cfd-online.com/Forums/ope...tml#post556013 - post #5

If you have some other machine, then the best I can suggest is as follows:

1. Follow the instructions given here: http://openfoamwiki.net/index.php/In...u#Ubuntu_14.04
2. But when you reach step #6, use the option for "i686", which should also work with "armvl7".
3. These instructions do provide the indication of what needs to be done for diagnosing problems with building OpenFOAM.

Beyond this, I have no idea what else is needed.

Best regards,
Bruno

[Hemanth]

Thanks Bruno,
Will try and let you the progress next weekend. How to whether system is rasberry pi or not ?

If you're able to look at the machine itself (the tower or box for the computer), then it's a Raspberry Pi if the contents of the box looks something like the images shown here: https://en.wikipedia.org/wiki/Raspberry_Pi - there is also a table there listing the physical dimensions of each version.

[leinad]

I have recently build a Raspberry Pi cluster, using Raspberry pi model b 2, i have Openfoam 2.4.0 running every thing works, I can put together a how to if any one is intrested

[Hemanth]

Hi Linead,
Can you post a step by step post for installing Openfoam2.4 on ARM architecture if possible.

[leinad]

Hi Hemanth

Yes that's not a problem I will put together a pdf as there are a few people who are interested. Depends how my workload is at work but hopefully I will get some thing on here within the next few days

[leinad]

To Hemanth and every one else that is looking to install OpenFoam on a Raspberry Pi, see attachment.
I hope it is useful to some one, if you like this tutorial and you have any knowledge of setting up a axial fan boundary condition please let me know as that is what i need help with

I followed the procedures and here is the zip file of make.log .
Can you help from this if you can ?

Hemanth
Try the instructions in the pdf I posted yesterday

Hi Daniel,
When i did ./Allwmake in the path sepecified in instructions, It throws an error .

./Allwmake: 4 : ./Allwmake: wmake chkPwd : not found
Error : Current directory is not $WM_PROJECT_DIR
The environment variables are inconsistent with the installation.
Check the Open FOAM entries in your dot-files and source them.

It might be because of the previous environment variables that are set during installation through the other method by Bruno.

Hi Hemanth
What os are you using ?
I would suggest you start with reinstalling your os so that every thing is default then try again

[mvbakker]

I just followed your tutorial. I only did not take the latest version of Rasbian but I took the one from May (Wheezy) since I assumed you used that one as well (Rasbian Jessie wasn't out when you guys had this discussion).

Unfortunately I got the exact same error as Hemanth. What should I do? Try it with Rasbian Jessie?

Did you succeed eventually Hemanth?

[leinad]

Strange that both of you are having troubbles. As two people have had the same error I will review the tutorial to make sure there are no errors and I will update. I am currently at the open foam user event and don't have the cluster to hand but I should get back to you by the end of the week

[mvbakker]

I am not sure yet but I might have fixed it by running:

source /home/pi/OpenFOAM/OpenFOAM-2.4.0/etc/bashrc

which loaded the environment variables (I guess, I'm also new to this). Now it is doing stuff after I ran:

/.Allwmake

Does this seem like a logical solution?
