Life is not only CFD and there is no clear divisions in life either. I like to share interesting things which I have been looking at; would you be interested in them also?

1. This Tech Bubble Is Different

I have been a programmer for years and I still have a clear idea on the internet bubble around 2000. Time flies and shortly after that one, we are in a next bubble which involves Facebook, Twitter and Groupon etc. If you like computer and internet technology, probably this article from Bloomberg would interest you.

1. Installation of Code_Saturne on Mandriva

A very helpful wiki page on how to compile and install Code_Saturne onto Mandriva has been contributed as follows

Since it is a French instruction, I also paste the Google translated English version here, as

2. A practical Code_Saturne study example

It is interesting to read a CFD example which combines the usage of SALOME, Code_Saturne and ParaView.

ParaView 3.10.0 is released

The ParaView team has announced the availability of the ParaView 3.10.0 final binaries for download on the ParaView download page.

http://paraview.org/paraview/resources/software.html

I repost the Release Notes from the email list as follows:

ParaView 3.10

This release features notable developments, including mechanisms to incorporate advanced rendering techniques, improved support for readers and several usability enhancements and bug fixes.

For the 3.10 release, we have added 60 new readers. The new readers include: ANSYS, CGNS, Chombo, Dyna3D, Enzo, Mili, Miranda, Nastran, Pixie, Samrai, Silo, and Tecplot Binary. A full listing of supported readers can be found in the ParaView Users Guide. We also added the ability for developers to create ParaView reader plugins from previously developed VisIt reader plugins. You can find a full guide on how to do this on the VisIt Database Bridge: http://www.paraview.org/Wiki/VisIt_Database_Bridge.

With this release we have rewritten the ParaView User's Guide and are making it freely available for the first time. The complete guide can be obtained in the help system or online at:
http://paraview.org/Wiki/ParaView/Users_Guide/Table_Of_Contents.

We have included a Python-based calculator which makes it possible to write operations using Python. The Python calculator uses NumPy, which lets you use advanced functions such as gradients, curls, and divergence easily in expressions. Also the NumPy module is packaged in the ParaView binary and is importable from the ParaView Python shell.

There should also be a marked performance improvement for users dealing with large multi-block datasets. We have cleaned up the rendering pipeline to better handle composite datasets, avoiding the appending of all blocks into a single dataset as was done previously.

To better utilize multiple cores on modern multi-core machines, by default ParaView can now run using a parallel server, even for the built-in mode. This enables the use of all the cores for parallel data processing, without requiring the user to start a parallel server. ParaView binaries will also be distributed using an MPI implementation, making this feature available to users by simply downloading the binaries. Since this is an experimental feature, it is off by default, but users can turn it on by checking the Auto-MPI checkbox in the application settings dialog.

Additionally, the 3.10 release includes several usability enhancements. 3D View now supports smart context menus, accessed by right-clicking on any object in the 3D View to change its color, representation, color map and visibility. Left-clicking on an object in the 3D View makes it active in the pipeline browser. Within the spreadsheet view, sorting is now supported and an advanced parallel sorting algorithm ensures that none of the benefits of the spreadsheet view, such as streaming and selection, are sacrificed. Python tracing and macro controls are no longer hidden on the Python shell dialog and instead are now easily found on the Tools menu.

For developers interested in adding support for advanced multi-pass rendering algorithms to ParaView, this release includes a major refactoring of ParaView's rendering pipeline. View and representations have been redesigned and users should see improved performance in client-server mode from reduced interprocess communication during rendering.

LANL's MantaView interactive ray tracing plugin has been restructured to make it easier to use. Version 2.0 of the plugin is now multi-view capable and no longer requires ParaView to be run in a client/server configuration. Similarly both of LANL's streaming aware ParaView derived applications have been merged into ParaView proper in the form of a new View plugin. The underlying streaming algorithms have been rewritten to be more usable and extensible. Both plugins are available in standard binary package for the first time in this release.

For an exhaustive list of the new features and bug-fixes, please refer to the change log at: http://www.paraview.org/Bug/changelog_page.php.

As always, we rely on your feedback to make ParaView better. Please use http://paraview.uservoice.com/ or click on the "Tell us what you think" link on paraview.org to leave your feedback and vote for new features.

Stable version Code_Saturne 2.0.1 is released

I am glad to let you know that the production release version Code_Saturne 2.0.1 can be downloaded from

http://research.edf.com/research-and-the-scientific-community/softwares/code-saturne/download-code-saturne-80059.html

I am curious that all the source code were packaged into zip format. When trying to compile the source code, unfortunately, an error could occur as

:/$ ./configure
Error: permission denied
# the solution
:/$ chmod +x configure

The easy solution is modifying the attributes of the configure file.

By this I succeeded to compile bft package; however when compiling fvm, I have got another error shown as

checking for bft version >= "1.0.0"... configure: error: in `/home/wu/saturne_packages/version 2.0.1/fvm-0.15.2':
configure: error: compatible bft version not found

I checked and found that the "make install" script of bft didn't install proper header files into the destination directory (by default, /usr/local/include). I guess this is a bug to fix, though the headers can also be copied manually.

I didn't try the rest of the compilation yet.

SALOME version 5.1.5 is released

Please read the piece of news.

CEA/DEN, EDF R&D and OPEN CASCADE are pleased to announce SALOME 5.1.5. It is a public maintenance release that contains the results of planned major and minor improvements and bug fixes against SALOME version 5.1.4 released in July 2010.

This new release of SALOME includes the following important new features and improvements:

• New operations in Geometry module: Automatic coordinate vectors and other.
• Export CAD models to VTK native format in Geometry module.
• New operations in Mesh module: Split hexahedrons to 24 tetrahedrons, Remove orphan nodes, Create boundary elements, Duplicate nodes / elements.
• Improved Quadrangle mapping meshing algorithm: new Reduced (layers) type of meshing.
• New filters in Mesh module: Coplanar faces.
• Graduated axes trihedron in the OCC viewer.
• Customizable shortcuts for some most frequently used operations.
• New features in YACS module.
• New TUI functions.
• Multi-language support (plus French resources).
• And more … see SALOME 5.1.5 Release Notes for details

SALOME 5.1.5 supports Debian 4.0 Etch 32bit and 64bit; both are Ubuntu compatible. The latest installation wizard packages can be retrieved from the download page of the official site. I expect the tutorial "Installation of SALOME 5.1.3 on Ubuntu 10.04 (64 bit)" would still be helpful when install the latest SALOME 5.1.5 onto Ubuntu 10.10. I also look forward to receiving your testing feedback on this.
