Hello everyone, I have spent some time this week trying to make foam-extend 4.0 work with my Ubuntu 20.04 installation. So I decided to share what I learned here and help other users. I created a git repository with the changes and steps needed to make it work: https://gitlab.com/serfriz/foam-extend-4.0-ubuntu-20.04

Please, note that my installation directory is ~/Apps/FOAM-Extend/ so if you want to install it in the default ~/foam/ folder you will have to modify the etc/bashrc file. Also, paraview is set to compile without python to avoid some compilation errors (I don't need it).

Please let me know if you have any questions!

Hi Sergio,

Brilliant, that's exactly what I was looking for, that'll save me loads of time (and frustration...), thanks a lot!

Just to let you know: to get the git clone working, I had to use the https-link, as the git version gave me a "Permission denied (publickey)" error. Could be a problem on my side, not sure, just thought I should let you know.

Best wishes,
Sita

Hi Sita, you are right, I just updated the readme file with the https link!


Thanks!

Sorry, I haven't tried with Linux Mint. Some of the steps include installing packages for Ubuntu, so they might not work with Linux Mint.

Out of curiosity: any reason for using 4.0 instead of 4.1?

Btw, I'm finishing up a script to build a Docker image with foam-extend 4.1 base on Ubuntu 18.04, and I already have a script for a CentOS image. I'll post the link here when I make sure everything runs smoothly.

I read there were still some bugs in foam-extend 4.1 and the library solids4foam is only fully compatible with foam-extend 4.0 (for now).

Hello


I tried to do it on ubuntu20.04, but failed.

Heelo serfriz,

Thank you for your post, this is exactly what i was looking for.

Unfortunately, i didn't succeed to compile, and my final output message was this:
Error: Current directory is not $WM_PROJECT_DIR
The environment variables are not consistent with the installation.
Please source configuration files.

Examples:
bash: . etc/bashrc
tcsh: source etc/cshrc

If you sourced the configuration files, please check the 'foamInstall' entry.

Whereas, i executed the commands in your tutorial line by line.
Do you mind, please, helping me finding the issue ?

I got the following output when sourcing:
wassim@MSI:~/Apps/FOAM-Extend/foam-extend-4.0$ source etc/bashrc
-bash: /home/wassim/foam/foam-extend-4.0/bin/foamCleanPath: No such file or directory

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

-bash: /home/wassim/foam/foam-extend-4.0/bin/foamCleanPath: No such file or directory
-bash: /home/wassim/foam/foam-extend-4.0/bin/foamCleanPath: No such file or directory
could it be the reason of failure ?

Can you be more specific on why it failed? You might be able to get some help this way...

Your environment variables seem to be configured wrong. I haven't looked at the tutorial you are following, but if you're running from a folder different from the standard one, you must modify your bashrc correctly. If I remember right, foam-extend does not recognise the the folder the installation files are located automatically, so anything different from the standard must be manually added.

Hello,


I have tried to intall foam-extend-4.0 using the gitlab link posted but have failed to be able to install correctly.


The code compiles and the installation process finishes, but whenever I go to try run a tutorial case and input the command blockMesh, I get an error sayingthat command does not exise.


I am running it on WSL Ubuntu 20.04.

[sita]

Hi Merlin,

Silly question perhaps, but have you sourced foam-extend first? That is, did you enter a command like

source $HOME/foam/foam-extend-4.0/etc/bashrc

or does your .bashrc contain a line like

alias fe40='source $HOME/foam/foam-extend-4.0/etc/bashrc'

and did you use this alias before trying to run a tutorial?

Sita

[MFWilliams]

Hi Sita,


Yes i think I did do that. I entered these lines of code which are quoted in the gitlab page:


source etc/bashrc
echo "alias fe40='source \$HOME/Apps/FOAM-Extend/foam-extend-4.0/etc/bashrc'" >> $HOME/.bashrc



And yes I checked using 'nano' that the bashrc contained this line:
alias fe40='source $HOME/foam/foam-extend-4.0/etc/bashrc'





Yes i also initialised the alias using fe40 when starting up a new window of Ubuntu.

[sita]

Ah, too bad, well, it was worth a try... In that case I'm afraid it's going to be harder to find out what's wrong with your install. What's the response if you enter something like

echo $WM_PROJECT

or

echo $WM_PROJECT_DIR

These commands should return "foam" and the install directory of foam-extend, respectively. If they return nothing, the foam-extend environment wasn't loaded properly, most likely.

Also, if you look through the log.firstInstall file you created when compiling foam-extend (Step 6 in the GitLab instructions), do you encounter any error messages?

Sorry I can't be of more help, good luck!

Sita

[MFWilliams]

I did get these errors when doing step 3 of the gitlab instructions:


The following packages have unmet dependencies:
mercurial : Depends: mercurial-common (= 5.3.1-1ubuntu1) but it is not going to be installed
Depends: python2 (< 2.8) but it is not going to be installed
Depends: python2 (>= 2.7~) but it is not going to be installed
Depends: python2:any (< 2.8)
Depends: python2:any (>= 2.7~)
python : PreDepends: python-minimal (= 2.7.11-1) but it is not going to be installed
Depends: libpython-stdlib (= 2.7.11-1) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.


Can anyone make any sense of this and help me out?

[MFWilliams]

Then I also got these errors when I inputted in 'source etc/bashrc':


-bash: /usr/bin/mpicc: No such file or directory
-bash: /usr/bin/mpicc: No such file or directory
-bash: /usr/bin/mpicc: No such file or directory
-bash: /usr/bin/mpicc: No such file or directory

Command 'mpicc' not found, but can be installed with:

sudo apt install lam4-dev # version 7.1.4-6build2, or
sudo apt install mpich # version 3.3.2-2build1
sudo apt install openmpi-bin # version 4.0.3-0ubuntu1


Again, can anybody help me with this?

[sita]

It looks like something went wrong when you tried to install the required libraries in step 3. Without these, your foam-extend install may fail (check the install log for errors to see whether this was indeed the case). Also, you seem to be missing mpicc, which means that you need to install one of the MPI packages listed in the error message (e.g. sudo apt install openmpi-bin openmpi-doc libopenmpi-dev).

I find it difficult to help you with this, but what you could try is to install the required libraries one by one, instead of all in one go (as is done in step 3 of the GitLab instructions). Then you can see for each package if anything goes wrong, and if so, whether you have a suitable alternative already installed (for example, my own Ubuntu 20.04 foam-extend install log says it used hg as a client for the mercurial stuff).

[MFWilliams]

Thank you for your help. I have managed to install correctly using the steps from the foam-extend 4.0 wiki page


My exact steps from a fresh installation of Ubuntu 20.04 to succesful compilation (without swak4foam) are listed in the attached document.

[serfriz]

Hey guys, sorry I haven't been very responsive, I saw some of you have issues with the installation directory and setting the environment variables. As I said in my first post, the repository is configured to install foam-extend in the directory "$HOME/Apps/FOAM-Extend/foam-extend-4.0", if you want to install it in the standard "$HOME/foam/foam-extend-4.0" you will have to modify the "etc/bashrc" file and the alias in "$HOME/.bashrc" to point to it. The line to modify is "foamInstall=$HOME/Apps/FOAM-ExtendfoamInstall=$HOME/Apps/FOAM-Extend"

Also make sure you source your $HOME/.bashrc and activate the environment with the alias before trying to run foam extend.
