Hi everyone

I have followed the instrucations on this page https://openfoamwiki.net/index.php/I...oam-extend-4.1 for the installation , but whenever I get to the source etc/bashrc line the terminal throws the errors listed below
bash: /opt/foam-extend-4.1/bin/foamGetSystemInfo: No such file or directory
bash: /opt/foam-extend-4.1/bin/foamCleanPath: No such file or directory
bash: /opt/foam-extend-4.1/bin/foamCleanPath: No such file or directory
bash: /opt/foam-extend-4.1/bin/foamCleanPath: No such file or directory
bash: /opt/foam-extend-4.1/etc/settings.sh: No such file or directory
bash: /opt/foam-extend-4.1/etc/aliases.sh: No such file or directory
bash: /opt/foam-extend-4.1/bin/foamCleanPath: No such file or directory
bash: /opt/foam-extend-4.1/bin/foamCleanPath: No such file or directory
bash: /opt/foam-extend-4.1/bin/foamCleanPath: No such file or directory

I have even tried looking on this forum How to install foam-extend 4.0 in UBUNTU 18.04, but still have no luck.

I then found this page https://pingpong.chalmers.se/public/...ml?language=en

followed those instrucations and I still get the same errors.

Can anyone please help me, and any other individual who is struggling with this. If it makes a difference I already have openFOAM v7 installed. I am fairly new to ubuntu and openfoam, so maybe I am misunderstanding something.

Thanks in advance

Depends on what you want. foam-extend and OpenFOAM-Foundation are not the same.

Might look at the links below for the foam-extend issue link, may be asking the installation question there might help?

Thanks, tried looking around at the forums you recommended. I've had no luck so far.
The thing is I can even install Foam-extend 4.0 but even that was giving me the same error.
I am busy doing a Udemy course and its focussed on materials as well as structure https://www.udemy.com/course/the-com...chanics/learn/
The instructor here uses Foam-extend 4.0, and I have even tried using his installation process(same as instructed on the site) but still got those errors.

I will try installing 4.0 via the .deb package and see if anything differs.

Thanks for the help.

The solution was to basically move my foam-extend folder from ~\foam\foam-extend-4.1 to opt\foam-extend-4.1.
Basically use sudo mkdir foam-extend-4.1 in the opt folder,
Then sudo chown (username)/opt/foam-extend-4.1
followed by mv ~/foam/foam-extend-4.1/* /opt/foam-extend-4.1/

This was suggested to me by someone on the openfoam discord server, it worked first time. Pity the installation instructions on the foam-extend page lead to something incorrect.

So you have two folders for extend 4.1? One in opt\ and one in ~/foam/foam-extend-4.1/ ?

Hi no it's only the one folder in the opt\ directory. From then on you can basically use the alias "fe41" to access the foam-extend environment through the terminal.

If I keep folder in opt and delete the other folder then still I get some error. Once I keep both then I do not see any error. It is a little confusing. Can you post all the steps that you followed?

What does the error say?

I will get back to you with the steps, it'd quite late where I am and don't have my PC on me. But I'll respond once I wake in the morning with regards to the steps. For the most part though I executed the EXACT steps I typed above.

The other thing you could do is access your bashrc file in your home directory and using a text editor of your choice create the bash alias in that file. Note this is a hidden text file so select the option to see hidden files and folders and look for the bashrc file. Then create the alias there.
Else I will reply in about 12-14 hours with guided steps.

Thank you for your concern. I am trying again and will post the error if encounter in this attempt.

If I copy only in opt folder then I get the following error:

bash: /home/sad/foam/foam-extend-4.0/bin/foamGetSystemInfo: No such file or directory
bash: /home/sad/foam/foam-extend-4.0/bin/foamCleanPath: No such file or directory
bash: /home/sad/foam/foam-extend-4.0/bin/foamCleanPath: No such file or directory
bash: /home/sad/foam/foam-extend-4.0/bin/foamCleanPath: No such file or directory
bash: /home/sad/foam/foam-extend-4.0/etc/settings.sh: No such file or directory

bash: /home/sad/foam/foam-extend-4.0/bin/foamCleanPath: No such file or directory
bash: /home/sad/foam/foam-extend-4.0/bin/foamCleanPath: No such file or directory


And if I save the folder in /home/sad then I get the following:
bash: /opt/foam-extend-4.0/bin/foamGetSystemInfo: No such file or directory
bash: /opt/foam-extend-4.0/bin/foamCleanPath: No such file or directory
bash: /opt/foam-extend-4.0/bin/foamCleanPath: No such file or directory

bash: /opt/foam-extend-4.0/etc/settings.sh: No such file or directory
bash: /opt/foam-extend-4.0/etc/aliases.sh: No such file or directory
bash: /opt/foam-extend-4.0/bin/foamCleanPath: No such file or directory
bash: /opt/foam-extend-4.0/bin/foamCleanPath: No such file or directory
bash: /opt/foam-extend-4.0/bin/foamCleanPath: No such file or directory

If I save copy in each folder and try to compile then my compilation works. I already added alias fe40='source /opt/foam-extend-4.0/etc/bashrc ' in my bashrc file.

[sadsid]

HI, I resolved the issue. I deleted both copies, restarted my system and downloaded the fresh copy in /opt folder. Now compilation is completed and alias--->fe40 is working perfectly.

I will now test some tutorials..

Thank you!!!

If you're still experiencing this issue with foam-extend-4.0 or foam-extend-5.0, it may be because the default installation directory is "~". Traditionally, students would compile in their home directory and run simulations on their desktop. 😄

For instance, the default installation directory for ESI is now in the /lib/ directory, while for Foundation, it's in /opt/. Apparently, they can't even agree on directories! 😄

Regarding the solution, if you install it in your home directory, there should be no issues. Otherwise, open the file foam-extend-5.0/etc/bashrc and either comment out or replace the line WM_PROJECT_DIR=$WM_PROJECT_INST_DIR/$WM_PROJECT-$WM_FORK-$WM_PROJECT_VERSION with WM_PROJECT_DIR=/opt/foam-extend-5.0 if you're installing it in /opt/. If it's another directory, just replace it with your chosen directory where you cloned it.
