Hello!

I am trying to install OpenFOAM 5 to use it with CFDEM-coupling on my laptop that is running Ubuntu 20.04.

I have copied the github repo, added the following line to the .bashrc:

source $HOME/OpenFOAM/OpenFOAM-5.x/etc/bashrc

Followed the instructions from https://www.cfdem.com/media/CFDEM/do...ng_Manual.html. Compiled using Allwmake and then I am receiving the error in the attached file. (I believe this is an error, as I am not able to run the tutorial cases in OpenFOAM folder)

I am wondering is it even possible to install OpenFOAM 5 on latest Ubuntu since it is not available as apt package anymore.

Thank you,
Azamat

I had the same problem. I solved it by installing OpenFOAM5.x instead of the version 5.0. Then in the thirdParty-5.x folder I replaced scotch_6.0.3 by the newer version scotch_6.0.9 (it is available on the more recent versions of OF). On the file scotch in the directory OpenFOAM-5.x/etc/config.sh/, the new version of scotch must be added (export SCOTCH_VERSION=scotch_6.0.9). Now both the thirdParty-5.x and the openFoam5.x compile well.

I want Helyx and Sim-Flow working on Xubuntu 20.04. This means that OF 4.1 has to be installed (which are not in the bionic or the focal repositories)
so although my distro is "focal" I enabled the following repositories - and I got OF 4.1 working.

Using synaptic I added:
deb http://dl.openfoam.org/ubuntu xenial main
(in order to install OF4.1) as well as
deb http://archive.ubuntu.com/ubuntu xenial main
(in order to satisfy the dependencies)

After installing OF4.1 I disabled the xenial repositories again.

Paraview did not work due to a 2011 intel integrated GPU on a hp 8440 laptop.

I enabled the oibaf repositories and got Paraview 5.4.1 going with :
/opt/ParaView-541/bin/paraview --mesa-llvm

You will need to read the error messages quite exactly. Some of the errors are indeed code errors in OpenFOAM (eg returning a value from a void method).
They didn't get noticed originally, but the newer compilers (like you have on ubuntu 20.04) do find them and flag them as an error.
So you will need to fix these manually.
Another possibility is to get the software working with a newer version of OpenFOAM. If you use the openfoam.com version, it always provides a version macro that you can use while updating your code. For example,

#if OPENFOAM > 1906
...updated code
#else
... old code
#endif

Can than create an upstream merge request with your changes.
If you want to try OpenFOAM-v1912 or v2006 on Ubuntu 20.04 see these instructions :

Thank you this worked!

Dear Tobias Holzmann,


Will this work as a rule of thumb for any other lower versions like v4. kindly suggest how to make lower versions like v4 work on ubuntu 22.04 or so
