Merge requests have now all been integrated in a new version of the foam-extend-3.1 nextRelease branch, which now constitutes a release candidate for version 3.2.

After some initial testing, the new foam-extend-3.1 code is now available here:
http://sourceforge.net/p/openfoam-extend/foam-extend-3.1/ci/nextRelease/tree/
i.e. it will remain in the nextRelease branch until the official release.
Click on History for the history of commits. The release notes will be updated during the testing period.

The next step is to test everything again thoroughly. We therefore invite the community to install the release candidate, run the test loop, and test your own cases.

This should be done by June 25, after which foam-extend-3.2 is officially released and merged to the master branch.

To clone a fresh working copy (and checkout the nextRelease branch):
mkdir ~/foam
cd ~/foam
git clone --branch nextRelease git://git.code.sf.net/p/openfoam-extend/foam-extend-3.1 foam-extend-3.1

To migrate from a previous foam-extend-3.1 working copy:
cd ~/foam
cd foam-extend-3.1
git pull
git checkout nextRelease
Note that work has been done also in ThirdParty, so it is a good idea to make sure that all those packages are re-compiled.

The installation instructions for Ubuntu 14.04 have been updated:
$WM_PROJECT_DIR/doc/buildInstructions/Ubuntu/Ubuntu_14.04
(during testing period: switch to nextRelease branch!)

Similar installation procedures as before applies for other architectures. If all required packages are installed, it is merely a matter of sourcing the etc/bashrc file:
. ~/foam/foam-extend-3.1/etc/bashrc
and doing:
foam
./Allwmake.firstInstall

Run the testHarness, following the instructions in
$WM_PROJECT_DIR/testHarness/README.txt

Hi,
thank's for the effort to al lthe developers. I installed without major problems on CentOS 6.6.

I had to install some dependencies:
yum install binutils-devel flex rpm-build qt-devel numpy
yum install mercurial openmpi openmpi-devel

I submitted a report to CDash:
http://openfoam-extend.sourceforge.n...tend-3.1&date=


1) During the build process only Foam2Ensight failed and produced errors which produced a error in the basic_laplacianFoam_flange_Allrun_oneTimeStep-test.
2) One CfMesh case was timed out (small memory)
3) The Wing motion case crashed incompressible_pimpleDyMFoam_wingMotion_Allrun_one TimeStep.

So far my first impressions.

Markus

Link is broken, it does not lead to bug tracker but to default page. Think it should be changed to http://sourceforge.net/p/openfoam-ex...extendrelease/.

[fguibault]

Thank you for mentionning this. The link has been corrected.

Hi Francois, and thank you very much for the job you made. I am a new user of Openfoam, I switched with it cause I want to compute a compressible flow with redlich-kwong equation for a shock tube.
I checked some extensions made by Chris Lucas about real gas equation but I don't how to add these extensions to Openfoam.

If you could provide more explanations of how to install these extensions please.

Thanks.

Dear Francois Guibault,

I have some difficulties compiling swak4foam (as well as for the foam source package) on my Mac OS X, so I tend to choose the pre-compiled package 'foam-extend-3.1.sparseimage'. And I noticed that, from the release notes as I attached, 'swak4foam' is included in this package. But I didn't find this tool...How can I start 'swak4foam'? or if there is actually no 'swak4foam' in this package, will it be included in the next release 'foam-extend-3.2.sparseimage' ? (may I ask when it will be released)

Looking forward to your reply. Any comments are appreciated!

Hi All,
I have had the same problem from the time foam extend 3.1 was released. I had to use a virtual Ubuntu to run cases that I need to use swak4foam or groovy bc. I wish this problem is solved in the next release.

Dear Francois,

I have tried to compile foam-extend-3.2 on 12.04LTS. The code (only src so far) does compile, but it takes a lot longer than usual. I have downloaded the code as described here:

http://www.cfd-online.com/Forums/ope...linux-mac.html

I have not changed anything in the settings, so I essentially follow the same steps as I always do. To visualise the severity of the problem, I have compiled waves2Foam on foam-extend-3.1 and foam-extend-3.2. Here are the results:

foam-extend-3.1: 3 minutes duration
foam-extend-3.2: 22 minutes duration

I have compiled both versions in Opt-mode, I am using the same Gcc-versions (Gcc 4.6.3) and I have compared the rules-files between fe-3.1 and fe-3.2 in the wmake/rules/linus64Gcc folder and I have not found any differences. Furthermore, for both versions of foam-extend I use 4 processors for the compilations (WM_NCOMPPROCS=4).

Have you or anyone else experienced this problem?

Kind regards,

Niels

Greetings to all!

@Niels: I experienced the same when trying to build the Fluid-Structure Interaction toolkit. The resulting object files don't seem much larger in 3.2 than in 3.1, but each class file takes way too long to build. I suspect that there is an infinite dependency "#include" loop, which is leading to this issue, but I haven't managed to get around to diagnosing it.

edit: Reported this issue just now here: https://sourceforge.net/p/openfoam-e...ndrelease/286/

@Yao Lu: A few questions:

1. Which Linux Distribution are you using?
2. What environment settings have you defined for building foam-extend?

Best regards,
Bruno

Hi Bruno,

I am glad to here that I am not the only one, who has experienced the decrease in compilation speed.

Next task is to find the issue. How should it be approached? Any information or task that we as a community could undertake?

Kind regards

Niels

P.S. I also experienced the slowdown with the compilation of the normal source and not only waves2Foam, so it is probably in a central location that the problem lies.

Bug report is already open and has a few more details: http://sourceforge.net/p/openfoam-ex...ndrelease/286/
Although I suspect we're both suffering the same issue because we're using Ubuntu 12.04 and GCC 4.6.3. I haven't tested yet with a more recent Linux Distribution and GCC version.

Best regards,
Bruno

I've built GCC 4.9.2 with the built-in 3rd capabilities that foam-extend has got and the timings improved a lot, therefore it looks like a bug or limitations in the GCC 4.6.3 stack we have on our Ubuntu 12.04 installations. More details on the bug report: https://sourceforge.net/p/openfoam-e...ease/286/#ab9b

[ngj]

Hi Bruno,

Thank you very much for sharing this.

I have tested the compilation with 4.9.2 this evening, and I can confirm your findings, a.k.a. a huge acceleration in the compilation speed, e.g. waves2Foam is now compiled within the 6 minutes. This is still slower than for foam-extend-3.1, but it is a more acceptable compilation time in comparison with gcc-4.6.3.

Kind regards,

Niels

Foam-extend 3.2 is now released. Please see announcement here:
http://www.cfd-online.com/Forums/ope...end-3-2-a.html

This release is compatible with swak4foam v0.3.2, as detailed in the release notes.
