I've been running OpenFOAM [OF] Foundation's OF 7-Dev on xUbuntu 18.0.4 (a LTS). I've been thinking strongly of installing ESI's OF v 2012. They have a compiled Debian/Ubuntu distro.

My laptop is happily running xUbuntu 18.0.4; xUbuntu is the same as Ubuntu but with the XFCE Desktop in place of Gnome.

But Open-CFD's instructions are for a Debian install. This is for their Debian/Ubuntu distro. My question is this?

Should I wipe out my Ubuntu Linux and install Debian? I guess I could probably make it work with Ubuntu but is this something that will plague me [no pun intended] for the rest of my days?

Debian is apparently a scientific related release of Linux. I've had some problems getting OF 7 to run on Ubuntu: which is why I'm using the Development version. Does anyone else have these problems? I'm kind of a newb.

Any thoughts? Of course I'll also lose my OpenFOAM v 7-Dev but I really don't have much under it.

Also under OF 7, I'm really lacking some heat transfer models I planned to use for my 1st OpenFoam simulation. I've heard Open-CFD 2012 has these models.

Bit confusing, but Ubuntu is a debian derivative. The esi-opencfd repos are most definitely for Ubuntu. I installed openfoam2012 on my Ubuntu laptop yesterday. Be sure to read the docs though, the packages are more finely grained than you may be used to. For example, the openfoam2012 package is runtime only, there are also -dev subpackages and tutorials subpackages according to the principle: only install what you need.

Hi Mark

Thanks for responding. My query was occasioned by finding that the ESI-openCFD distro was labeled for Debian/Ubuntu. However, looking at the instructions I saw that everything talked about Debian libraries and repositories and there was nothing found for Ubuntu.

I also emailed ESI support and Mark of ESI {same 1st & last name: possibly related?} replied back saying the same as you. Ubuntu is a Debian derivative and they need to update their instructions so as to mention Ubuntu more clearly.

As you know Ubuntu is supposedly a little better in supporting various computer drivers and installs with xUbuntu 18.0.4 64bit pick up all my networking and devices flawlessly.

Thanks very much; I'm going to try to install Open-CFD OF v 2012 today on my xUbuntu. I'll have at least 3 computers running OpenFOAM so I wanted to get it right to start with. Two are running xUbuntu now.

yours,
John

Thanks very much. With great trepidation {recalling my OpenFOAM-7 install} I tried it. I substituted "2012" for "2006" in the command:

sudo apt-get install openfoam2006-default (after doing the repository key thing)
and it seemed to complete without giving any error messages.

Thanks very much!

Thanks very much!

We have discovered a build issue (https://develop.openfoam.com/Develop.../-/issues/1970) which is now solved, but may take a few days to get rolled out. Almost everyone is on holidays (or were on holidays, before patching builds). A build 1-2 is in the offing.

it says:
"The dummy Pstream library cannot be used in parallel mode [for v 2012]"

Something about mpirun which I presume means "multiprocessor something". Okay noted.

I don't expect to get into running multiprocessor threads for a few weeks at least.

Thanks for letting me know.
