PHP problems

Posted on | May 6, 2014 | Comments Off

My blog had some problems due to a PHP update performed by my host which broke the wordpress theme in use. I replaced the theme with a temporary one while I find a solution. I hope this does not cause too many troubles!

GeekoCFD 6.0.1 is now available for download

Posted on | January 10, 2014 | 5 Comments

I am pleased to announce the release of GeekoCFD 6.0.1, based on the new openSUSE 13.1. You can download it directly from the SUSE Gallery page.

GeekoCFD 6.0.1 brings the following updates:

  • CFD and C++ development applications
    • OpenFOAM 2.2.x, with x > 2. The repository release of OpenFOAM includes the latest updates and bug fixes made to OpenFOAM by its developers.
    • gmsh 2.8.3, the latest version of the gmsh mesh generation tool.
    • Eclipse Kepler SR1 with CDT
  • Base openSUSE system
    • Linux kernel 3.11.
    • glibc 2.18.
    • gcc 4.8.
    • YaST 3.0, rewritten in Ruby.
    • KDE 4.11.
    • Qt 5.1.1 and 4.8.5.
    • LibreOffice 4.1.
  • Dropped packages
    • Helyx OS: the package has been split into a core component (kernel) and the GUI. The kernel component requires root access to operate. For this reason it has been dropped until further consideration.
    • QtOctave: the RPM is not available for openSUSE 13.1.

The openSUSE 13.1 release comes with Evergreen extended support, which will prolong its life after the standard end-of-life period of 18 months. GeekoCFD strictly follows the regular openSUSE release cycle, however users interested in a longer life cycle of their distribution can rely on the Evergreen project, which will start supporting openSUSE 13.1 at the end of its officially supported life-cycle in May 2015, and will continue supporting it until November 2016.

Finally some statistics: GeekoCFD has been downloaded a total of 4446 times and cloned 151 times at the time this announcement was written. Thank you for your support, and for your precious feedback.

P.S. The comment page on SUSE Studio has some spam. The SUSE Studio team is working on a permanent solution. Please, be patient while this problem is being addressed! The SUSE Studio developers are great, and they provide all the infrastructure at no cost too. Thanks!

Enjoy :-)

Installing OpenFOAM 2.2.x on openSUSE 12.3

Posted on | April 7, 2013 | 2 Comments

The following procedure illustrates how to install OpenFOAM 2.2.x from the git repository on openSUSE 12.3, for the current users.

  1. Install the C/C++ development pattern:
    • zypper install -t pattern devel_C_C++
  2. Install other dependencies (gnuplot is optional, but useful):
    • zypper install cmake gnuplot openmpi openmpi-devel git-core
    • zypper install libqt4-devel libQtWebKit-devel libQtAssistantClient4
  3. Check that openmpi 1.6 is selected as default with:
    • mpi-selector --list
    • The output should read: “openmpi-1.6″. If not, use mpi-selector to configure the default version of openmpi (this can be done for the individual user or system-wide, acquiring administrative rights)
  4. Create the OpenFOAM directory in your home directory:
    • mkdir ~/OpenFOAM
  5. Move to the OpenFOAM directory:
    • cd ~/OpenFOAM
  6. Download the source code from the git repository:
    • git clone http://github.com/OpenFOAM/OpenFOAM-2.2.x.git
  7. Download the ThirdParty package from here (command on a single line) :
    • wget -c downloads.sourceforge.net/foam/ThirdParty-2.2.0.tgz?use_mirror=mesh -O ThirdParty-2.2.0.gtgz
  8. Extract the ThirdParty package and rename it as follows:
    • tar xzf ThirdParty-2.2.0.gtgz
    • mv ThirdParty-2.2.0 ThirdParty-2.2.x
  9. Add this  prefs.sh file to the directory:
    • ~/OpenFOAM/OpenFOAM-2.2.x/etc/
  10. Add the following line to your ~/.bashrc file:
    • [Optional for multi-core compilation, replace 4 with the number of cores you want to use]: export WM_NCOMPPROCS=4
    • source $HOME/OpenFOAM/OpenFOAM-2.2.x/etc/bashrc
  11. Open a new terminal and execute this sequence of commands to compile the whole OpenFOAM suite
    • source ~/.bashrc
    • cd ~/OpenFOAM/OpenFOAM-2.2.x
    • ./Allwmake
  12. To build paraview and its reader:
    • cd ~/OpenFOAM/ThirdParty-2.2.x
    • ./makeParaView
    • cd $FOAM_UTILITIES/postProcessing/graphics/PV3Readers/
    • ./Allwclean
    • ./Allwmake
  13. At this point OpenFOAM 2.2.x should be fully functional on your openSUSE 12.3. The installation can be updated, as usual, with:
    • cd ~/OpenFOAM/OpenFOAM-2.2.x
    • git pull
    • wcleanLnIncludeAll
    • ./Allwmake

Note: If you have an accelerated video card, like nVidia or ATI, it is strongly recommended to install the corresponding proprietary driver.

Enjoy :-)

GeekoCFD 4.0.0 text mode released

Posted on | September 9, 2012 | Comments Off

Following the release of GeekoCFD 4.0.0, also GeekoCFD 4.0.0 text mode was upgraded to openSUSE 12.2, and it is now available on SUSE Gallery. This version of GeekoCFD is thought to provide direct access to open-source CFD tools on systems without graphical interface, typically used to perform simulations.

GeekoCFD 4.0.0 released

Posted on | September 8, 2012 | Comments Off

GeekoCFD 4.0.0 is now available for download from SUSE Gallery. The release is based on the recently released openSUSE 12.2, and relies on updated versions of all major applications and system components.

The most important changes and additional features are:

  • Updated version of OpenFOAM® 2.1.x (x > 1, Including commit 969dc72c1aad45b98224e74917984401bdc76b82 – Wed Aug 29 2012)
  • Upgraded packages according to openSUSE 12.2 release
  • Re-introduced selection of octave-forge packages
  • New Hyper-V image added to the choice of virtual images

Additionally, some decisions on future developments were taken:

  • The release of GeekoCFD 4.0.0 signs the end of life of GeekoCFD 2.2.0, since its base distribution, openSUSE 11.4 will stop being supported two months after the release of openSUSE 12.2.
  • The 32-bit release of GeekoCFD is dropped. Starting with the release of GeekoCFD 4.0.0 and GeekoCFD text mode, only the 64-bit version will be maintained. This was decided based both on time constraints and on the fact that the number of downloads of GeekoCFD is significantly higher than the one of GeekoCFD 32-bit. Most of the recent machines are capable of running 64-bit operating systems, also in virtual environments. In case there is a need for a 32-bit version, please let me know.

A summary of the features of this release follows:

  • System
    • OpenSUSE 12.2 – 64 bit
    • Kernel 3.4.6
    • gcc 4.7.1
    • KDE 4.8.4
  • Scientific software
    • cantor
    • gmsh 2.6.1
    • grace
    • gsl
    • wxMaxima and Maxima
    • Octave and an almost complete selection of packages from octave-forge
    • opendx
    • OpenFOAM® 2.1.x
    • Paraview 3.12
    • pyFoam
    • R
  • Development tools
    • DDD 3.3.12
    • Eclipse Juno with CDT
    • Emacs
    • git
    • kate
    • vim with gitdiff
    • kompare
  • Other software
    • Blender
    • Firefox 15.0
    • Gimp 2.8.0
    • ImageMagick
    • LibreOffice 3.5

As usual, thanks to the SUSE Studio team and to the openSUSE project, without whom the creation of GeekoCFD would have not been possible without SUSE Studio and the openSUSE project.
