    Goodbye GeekoCFD

    I created GeekoCFD (first release on September 2nd, 2010) with the idea of simplifying the adoption of openSUSE for computing and, in particular, for computational fluid dynamics. It included one of the most popular open-source tools for computational fluid dynamics, OpenFOAM®, computer algebra systems such as octave and wxMaxima, and integrated development environments as Eclipse, in addition to a set libraries commonly used in HPC. At the time when I started to work on GeekoCFD, these packages were either not available on openSUSE, or difficult to build on it, while they were readily available on competing distributions. SUSE Studio, a web-based and user-friendly tool to build customizes Linux images in…

    GeekoCFD – Status update

    Currently, GeekoCFD images are not available on SUSE Studio, and an error 500 page is shown. I am looking into the cause of this. This may be related to the migration of SUSE Studio to Studio Express. Please, stay tuned for status updates. Updates (reverse chronological order) Latest update, Dec. 26th, 2017: GeekoCFD project ends. See the announcement. Update Dec 8th, 2017: It was announced that SUSE Studio will be shutdown on Feb. 15th, 2018. Official announcement from Studio developers here. Update Dec. 2nd, 2017: The migration of GeekoCFD to the Studio Express infrastructure is still ongoing. At the moment, several attempts to perform the migration have not been successful…

    GeekoCFD 7.0.0 is here!

    I am pleased to announce the availability of GeekoCFD 7.0.0. This release is based on openSUSE Leap 42.1, the new release of openSUSE based on the core of SUSE Linux Enterprise, and enjoys long-term support (and a beautiful artwork!). GeekoCFD 7.0.0 also brings the following major changes: Updated features UEFI and secure boot support enabled on USB disk images and Live DVD (not virtual formats). This change may make the specified images unbootable on systems which do not support UEFI and secure boot.

    Installing OpenFOAM 2.1.x on openSUSE 12.1

    OpenFOAM® 2.1.x has just been released, and brings an interesting number of new functions concerning arbitrary mesh interface (AMI), multiphase solvers, turbulence modeling, improved run-time control and new numerical methods. Assuming that OpenFOAM will be installed in the user’s home directory, the procedure to install OpenFOAM 2.1.x (git version) on openSUSE 12.1 is then as follows: Install the C/C++ development pattern: zypper install -t pattern devel_C_C++ Install other dependencies (gnuplot is optional, but useful): zypper install cmake libqt4-devel gnuplot openmpi openmpi-devel git-core Make sure git is installed zypper install git-core Check that openmpi 1.4.3 is selected as default with: mpi-selector --list The output should read: “openmpi-1.4.3”. If not, use mpi-selector to configure the default version of openmpi (this…

    GeekoCFD updated, GeekoCFD text mode released

    I am pleased to announce the release of GeekoCFD 2.2.0, which brings an updated image with OpenFOAM® 2.0.x (x >= 1), an updated ThirdParty package for OpenFOAM and openSUSE security updates, including Firefox 5. The images can be downloaded from SUSE Studio. Additionally, GeekoCFD 2.2.0 brings a smaller version: GeekoCFD text mode, which provides easy access to OpenFOAM for systems without a graphical user interface. GeekoCFD text mode is based on openSUSE 11.4 JeOS (Just enough operating system) 64 bit, and only provides the base system, the C/C++ development tools, and OpenFOAM, with its dependencies.As a consequence, the disk space requirements are significantly smaller if compared to the full version…

    Installing OpenFOAM 1.7.x on openSUSE 11.4

    The installation of OpenFOAM® 1.7.x on the freshly released openSUSE 11.4 is straighforward, however some care is required to have a working ParaView. The ThirdParty package provided with OpenFOAM ships ParaView 3.8.0, which does not successfully build with Qt 4.7. The steps for the installation on openSUSE 11.4 – 64 bit are summarized as follows: Use YaST to install the C/C++ development pattern in YaST cmake libqt4-devel (required to build paraview) libQtWebKit-devel (required to build paraview) libQtAssistantClient4 flex git Create a directory called OpenFOAM in your home directory mkdir ~/OpenFOAM Enter the OpenFOAM directory cd ~/OpenFOAM Download the source code: with the command: git clone http://github.com/OpenCFD/OpenFOAM-1.7.x.git Download both the OpenFOAM…

    R is there, a bit hidden…

    R is available for openSUSE and SUSE Linux Enterprise on the openSUSE Build Service. Unfortunately it is not so easy to find because the search engine requires more than two letters in the search. However, you can find a complete list of 1-click install links here. Thanks to Detlef Steuer who took care of preparing the page 🙂

    Decision taken: openSUSE defaults to KDE

    The openSUSE management took the decision of pre-selecting KDE as default desktop environment. This will be done by pre-selecting the KDE radio button in the current desktop selection screen, presented to the user at installation time. What does this mean? Nothing, for many users absolutely nothing. If a user will click “next” in the selection screen, KDE will be installed by default, but it will be possible to select GNOME with a simple click. The only thing this long and frustrating discussion showed are the old tensions in the community about a question that should have been considered as resolved long ago, in the interest of the community itself. Old…

    OpenSUSE: doing it wrong again!

    A very long discussion on making KDE the default desktop in openSUSE is taking place, digging out a problem that probably many of us considered resolved, but clearly was not. Many KDE users and developers feel KDE should be the default desktop for openSUSE, because the majority of openSUSE users, according to a survey conducted last year, choose KDE (GNOME has a user share slightly higher than 27%). The proposal, after a long discussion is to Pre-select the button of KDE, keeping the alphabetical order of the desktop environments, so that a user who clicks “Next” during the installation process automatically selects KDE Make a formal statement that GNOME is…
